Day 69: Neurology – Watch Videos

this is the best lecture i ever came across,what i aslo love about him is that he explains evrything slow n this helps me to process what hes saying

thank you for clear and detailed information on human brain

There were good pictures and diagrams but without a pointer showing what structure he's referring the whole lecture was hard to follow. I read through the transcript too and I feel like the explanations did not really match what was being showed on the slides (he kept talking about the numbers and diameters of things which were not shown on the slides).

yes i like too much like its so good and so clear

please use some pointers to show that part in the image. it will be easy for us to recognise it easily and it will be of great help. thank you

Very detailed inormation, helps to get good understanding, thank You!

Ich finde die Videos sehr didaktisch. Das Material ist auf einem hervorragenden Niveau.

I appreciate the fact they try to explain the processes in very engaging way, but i think it would be even better to use customized stock video of the development of the nervous system. I had to go watch one on youtube

Gives a thorough review of the head and neck material

1.To improve my clinical studies 2. Medicine require every day study and practice. 3 Public health development. Lecturio provides the best Medicine ???? carrier for all Medicine students and other health professionals. Anyone can be my Lecturer

Very useful, especially for those who are currently studying, and the pictures are clear, I wish that such videos were available earlier during my studies at the college

It's amazing, I really like explanations and how doctors express themselves

I like dr. Craig Canby’s understanding methods. And his simple, Clare English tone! Graphic of Lecturio.com and details of your level in chapter and subject at all play to make I continue watching!

An excellent course and therefore I gave the highest possible rating. I liked absolutely everything. Thanks for your work! I am now preparing for USMLE step 1 and I am at the stage of repetition of anatomy and embryology.

I like it but sometimes app is getting struck majorly.

excellent, makes it very simple. gives you a great overview, even if your class goes into more detail.

The videos and intermediate questions are amazing and very helpful

the lecture is good but for future can you include a slightly more advanced serioes that includes regiratory mediatory that can lead to congenital defects?

Best out there,these are short and precise .Full of information that we need

It’s not bad but compared to other sources seems like it is missing some info

I like it because its very useful to review specific contents, and is divided in a very good way

The circle of Willis was not explained. The video basically just says the vertebral arteries and internal carotids give rise to the circle of Willis. What about all the other branches?

Very nice explanation but please include more assessment. Besides objective questions, include subjective questions and give answers and ask the individual to self evaluate! A very helpful and intuitive way i think. Please implement at the earliest

Wow!...great stuff Nice mnemonic you have got for us sir.

Me ha gustado mucho la síntesis del tema y como lo ha explicado. Gracias

Very informative, and helped me with my studies. Has a lot of information I needed.

The sound quality is not good at some points in this video! please fix this issue...

Actually embryology is tough and it involves a lot of imagination if we study it on our own it is difficult to visualise but Sir makes the classes very interesting less of a burden and because of the classes I never had difficulty in this zone and this was the subject I didn’t had to look behind to review because once taught by Sir it remains forever . My favourite teacher

like as'e ddf ka0-wfjpA WEFJ- QW EG JFPWIO

Professor Canby is very thorough and presents a detailed explanation and caption of the head and neck anatomy along with some helpful mnemonics

I like this Guy I am the Last Hope Yes Yeah Si SIp

Content is very high yielding but the lecturer is slow to respond to qns

point to points clinical oriented lecture. clear cut explanation of topic.

Explanations are simple, comprehensive and concise. I would recommend this to students who are struggling with Anatomy during med school days. I was able to appreciate Anatomy more through the lectures in Lecturio.

Since there was a confusion regarding the actions of ocular muscles versus the cardinal gazes of movement when examining the intactness of ocular muscles, the video regarding this topic should be updated. And examples of exam questions pertaining between the difference of the two should be given. But overall, it was a good review!

Made it simple to understand and a lot more fun to learn!!!

Your program is perfectly designed for medical students I used it for one day and i really liked it unfortunately due to my financial issues I wasn’t able to continue it but I recommend it for all you guys to take advantage of it

I'm so disappointed about this lecture. I feel it just described briefly about head and neck. It didn't describe about bone of head and neck, muscle,....

Brilliantly done! This course is so useful Unbelievable good!!! As I am a foreign graduate I had to re listen to make sure I lent correct pronunciation!! A very well done and I can’t thank enough for design patterns and overall greatness!

I could easily understand the theory with diagram and make notes

Genica Quilatan I like how Dr Canby discusses the main points. I wish him more power and I hope he continues to do this. Helps us a lot!

Thank you very much. I like this whole review program.

It is clear, well explained and very useful. Totally recommended.

elegí ésta calificación por que explicó de manera clara y sensilla el tema, ahora puedo profundizar mas el tema leyendo un libro. Me encantó la conferencia. Sí recomendaría este video a todos mis compañeros de clase

Elegí esta calificación porque explicó de forma sensilla de entener y recordar lo básico del desarrollo y patologias de los arcos faríngeos, ahora queda ib¿vestigar más sobre dicha información. Me gustó que pone la variedad y cantidad de imagenes que proyecta justo en el momento exacto que explica, eso hace más entendible la conferencia. Recomendaría este vídeos a mis compañeros de facultad.

Thank you for a very interesting lectures. Very easy to understand with your explanation

Hi All components of both head and neck anatomy were clearly presented especially cervical triangles whichi was pretty updated.

well explained. its concise and not overcomplicated. has everything you need and is well taught

Histology explained really well. At each step letting us know what is going to be explained is really good.

The confidence from Dr. Canby as many other Lecturio Presenters reassures the average student. I am particularly satisfied with the way the Lecturio courses are designed and presented. I highly rate this course because it is up to my expectation. If a student doesn't learn anatomy from this course he/she won't learn anywhere else.

I chose this rating because you deserve it! Thank you, everything is great!

It's An Good Overview And Histological Studies Of Ganglion.,But There is Need to Tell Stains Name

i like the videos very much because of the clear presentations

it is self explanatory and so understandable , i like this a lot

The Proffessor Peter Ward is the best for embryo. I really enjoy and learn of this lecture

Head and neck anatomy is presented concisely, very helpful and clear, easy to understand and remember.

Dr. Meyer is a great teacher, a lot from my experience with his videos regarding the introduction to the mammalian cell however, this video definitely left a lot to be discerned and was not very informative. Required me to do a lot of googling to make sense of much of these... Hard to follow and disappointing.

Excellent overview. The clinical considerations were also very beneficial. Thank you Dr Canby.

Very precise and short not too lengthy! Very good explanations

Dr. Meyer is great! His lectures help me so much in preparing for class and understanding. I have really struggled with the eye, so this was a life-saver.

I truly appreciate Dr. Ward's efforts on making these lectures, guiding me through development of multi organ systems. Highly recommended!

it covers most of the embryology of nervous system. I think it will be really perfect if there are more details on the development of brain itself, specifically cerebellum and midbrain. Another thing to be noted, I cant find the development of spinal cord and it is a part of nervous system. In the end, thank you d.Ward for those really amazing lectures

i like how he explained topic and also answered the questions

I liked it because he explained all very interesting and detailed

Buetiful app for refreshing the course quickly. I would recommend it to all my colleagues

Everything is very clear and well-structured. I love it. I would absolutely recommend it to anyone else studying medicine.

amazing and well-thought lecture. explains extremely long pages of gray's anatomy within minutes. it is so much easier to read anatomy and go through studying it and memorizing instead of taking precious time to understand what the author wanted to say...

Very helpful. I think it will be better with more clinical case.

because the lecture is short and brief it is also not time consuming

super tough course. I'll definitely come back to it and view it again. These videos are a little bit fast paced for me

it was great.the pacing of the lecturer was okay it gives me time to imagine the structures since this is anatomy (pure memorization).Thank you

Le he dado 5 estrellas a esta conferencia porque es una conferencia que realmente se lo merece, explica muy bien el tema y he aprendido bastante acerca de este tema muchas gracias profesor

I never enjoyed a lecture about embriology like this before. love it!

Best diagram and explanation ever received. None of my teachers could explain so clear this concept. Thanks Dr. Meyer

Many Of The Topics Are Not Covered For Example Osteology Of Bones Of Skull Cranium And Viscerocranium Too Arteries Anatomy of Eye,Ear And Tongue And So On

Very good informative simple clear direct to the point contain everything

Anatomy lectures are very well explained and hence I am delighted and very appreciative,the diagrams are very clear.

If you are going to go into haemorrhages and this is Anatomy the different layers of the meninges should at least be mentioned.

Most of the topics are explained well. Although there are still many topics which needed to have more content and the overall integration of all the brain structures and functions is lacking.

I liked the course wholly and i would recommend it for my friends

I love this app but wish I can watch the video from one to the next without stopping for the quizzes then take the quiz at the end of the topic being reviewed.

this is such an amazing, succinct playlist which is really exclusive and pretty different from what I have learnt in my university

Great lecture! straight to the point and extremely informative. thank you so much for so many amazing teachers.

Manifold information was expressed pretty clearly, making me grasp almost the necessary knowledge of Intracranial hemorrhage.

Here is a quote from which describes Lecturio: "In order to take on this challenge, Lecturio created a high-quality digital medical education resource, which is affordable, adaptive, and personalized. We designed our platform with the needs of learners and faculty in mind, combined with the latest state-of-the-art learning technology and comprehensive monitoring and assessment features." The lecturer keeps saying that he is going to have the "anatomists" explain the structure in detail...so why are we wasting our money looking at this. I paid for a subscription to this site for "state-of-the-art learning technology." If a customer clicks on the video to see a presentation on the general structure of the eye, they shouldn't have to waste their time watching a PowerPoint with no pictures of the eye. It is an insult for customers to have this guy put up this type of presentation. My textbooks have better supplemental material .

This is what you read on Lecturio's site: "In order to take on this challenge, Lecturio created a high-quality digital medical education resource, which is affordable, adaptive, and personalized. We designed our platform with the needs of learners and faculty in mind, combined with the latest state-of-the-art learning technology and comprehensive monitoring and assessment features." STATE OF THE ART??? These are PowerPoint slides!!! The guy is talking about different structures and you have to pause the video to find what he is trying to reference! Get a pointer. Use an arrow. Show the viewer the exact location you want to emphasize. If I turned this type of presentation in for a grade, I would get it returned. Kahn Academy, Ken Hub...this is as low tech as you can get. I expected so much more. You are supposed to save us time. I hate writing this but other people have to know that this lecturer's delivery - I might as well get a text book out and read it to myself.

Excellent thank you. Thank you Dr. Craig, this video is very helpful.

very good initiative. very useful. 3d animation is very impressive. good luck.

I really like it. It’s clearer than a lot of textbooks making it easier and quicker to understand. Professor Canby does a great job at explaining.

Elegí esta calificación porque me permite estudiar más rápido y lo entiendo muy bien. Me gustó porque explican a detalle cada estructura expuesta. Recomiendo este curso a todos los estudiantes de medicina humana.

Everything told was in a different way that I liked the most.It clears all my major doubts arise from reading books related to head and neck anatomy.There is no better app than this.

Personally, I enjoyed the entire Histology review a lot, and would like to take this opportunity to thank Prof. G. Meyer for these lectures. All the best, Liliana B.

great, but first watch the previous videos! made the difficult matter seem a lot easier

This series of lectures about the ear really need to be addressed, they make no sense, if you don't already have a complex knowledge of the ear. Once you have that this I guess is a good way to review, but then why am I paying for this for 2 years? If this is how it is supposed to be lecturio should be advertised as step prep company only, not as a supplement to lectures. Disappointed in the ear and hearing series of lectures.

I've watched this video 3 times and can not follow it. I expect better from this company.

It was really good and really well explained so thank you It was fun to learn

Very good Please give another day for free primium So that we can know more

Excellent. It would be good to have some cadaver explanatory session to create a more realistic view. Well tutored.

Clear and concise lecture. Way to follow. Additional articles available if you need extra detail. Using video format suits me a I can pause and replay when I miss something.

Some key topics not explained:- Triangles of neck,muscles of mastication,temporal and infratemporal fossa , osteology of skull,muscles of face,submandibular gland,parotid gland

Excellent presentation. Good content Illustrations are very good Font size of the letters should be higher

Very helpful in conjunction with my textbook readings; the drawings really help with solidifying what's being discussed by giving me something to visually refer to in my mind. Peter is also kawaii and you can tell he's really genuinely passionate about this topic, which made me enjoy watching these in my studies even more. (? ?•???•? ?) Thanks for all the effort.

Really engaging, easy to remember But number of question is still little

Very nice presentation and easy to learn platform Which make preparations for USMLE enjoyable

Very nice presentation and easy to learn platform Which make preparations for USMLE enjoyable

Absolutely amazing source of learning Head and Neck Anatomy, would definitely recommend this to everyone and anyone in medical field

I just finished my first year of medical school and I’m reviewing over the summer. These videos are concise and to the point. I like how the questions are directly following. Very helpful, I wish I knew about it during school as well

The slow and steady way of explaining every single detail is really appreciable

Awesome well done. Highly recommend it lecture was clear and easy to understand

He explained thoroughly and I was able to understand without having to use the lecture. I really like the quizzes that are given. wish the quiz had more questions though

I like the slow and convincing way of teaching and obviously this is so good

Just what I have been looking for since I decided to go into the medical field. Just perfect for all my needs. Thanks

This lectur have all about anterior and posterior triangle in an easy way.

I personally didn't found these lectures much informative, the speed of the professor is extremely slow plus the slides provided in it has more than 55 pages lot of times for a single lecture instead of compiling it in a good way. Must work with the slides provided in the download items. The lecture would be useful if it would have engaged the whole thing clinically like which le forte fracture will be associated with rhinorrhea, etc.

Thank you sir for keeping it simple and easy to understand!

i liked the clinical correlations and the emergency incisions which was clearly explained.

Not detailed at all! Especially when compared to other lectures. Was lacking a lot of anatomical learning points

Just AMAZING!!!! Thank you Dr Peter for making this lecture so easy. This made me understand more rather than mugging up the derivatives.

good job loved it easy abdsorbing and can understand english very well

great explanation and quiz is the best part of the lectures

Very nice explanation Easy approach Perfect timing Thank you Professor

thanks, it is very clear, helpful and understandable for everyone.

I think is very useful and everyone can understand the information... Great!

All lectures are easy to understand, memorize and quizzes are helpful. Keep up the good work.

I really like the making of the content of the lecture so short and placing only the most important facts However, I feel that it would increase the understanding if an animation would be involved

Simple was easy to understand Quiz help to assess oneself

It was really helpful, I would recommend this as an auxilary tool to follow up with your text books and class notes.

Rere and nice topic with a considerable difficulty which is lectured here with high accuracy and clarity

Good presentation, very accurately illustrsatrd and useful for all medical and theraptic ppurpose

This sirgical technique is taught wih prompt accracy , a nice discription.

A realistic approach for educate all medical professionals . Acurate and elabotate , made it suitable for medical needs

really an exlent way of art of teaching and presentation which is highly reguired for proper orientation and clear understanding

Nice presentation with required accuracy and elaborative that makes it vefy easily understandabe for any one

Image quality is a little issue here otherwise all fine and lectures are great

Me gusto todo, simplemente que en la pregunta que dice cuales son los músculos que desvían el ojo hacia abajo me dio como incorrecta cuando puse que eran el oblícuo sup y el recto inferior.

The course doesn't include various topics like temporal, infratemporal and pterygopalatine fossae, temporomandibular joint, origin and insertion of muscles of neck, parotid region, submandibular region, pharynx (the pharynx covered in abdomen doesn't cover much details), blood supply and lymphatic drainage of head and neck, etc

great job, thank you for the details! if there are updates, it is much appreciated

Thank you very much, that was clear and to the point

Good video to see and really simple to understand and not confusing, really helpful for anatomy's lab and for life.

Great course and simplified embryology. Made studying and tying the material together so much easier.

Me encanta sus clases son mas explicitas y entiendo mejor cada paso para realizar los procedimientos

Bcz it's very helpfull and the teaching method is very good.

Great lecture with in depth knowledge! Easy to understand and follow the lecture

excellent presentation and clarification of both structures and function of the Nervous system. Thank you.

I choose this rating because it was truly clear, and i remembered it right away. I would recommend this video to students of Osteopathy.

Thank you Dr. Craig, this video is very helpful! I learned everything necessary that I need and I'm glad...

Clear presentation, well oriented, easy to follow, well illustrated, takes you to clinical applications almost inmidiatly, great to review your complex isolated concepts of neck anatomy.

Some of these comments are absurd, no where in the video does the professor say interior oblique. Great video, straight to the point with great illustrations. Thank you!

Lecturio should open their own medical school in the Caribbean and people could actually learn down there ! keep it up !

Very less content... Try to upload many more vedios.... And on much more details

They are great but it would be better if explained some of the cellular development behaviors involved

clear and well summarized, the quizes at the end are very helpful for memorizing

Lectures are very dry, provide no interesting insights and focus very strongly on anatomical labels (eg. focus on learning names of parts rather than giving a good knowledge and feel of those parts).

The course doesn't include various topics like temporal, infratemporal and pterygopalatine fossae, temporomandibular joint, origin and insertion of muscles of neck, parotid region, submandibular region, pharynx (the pharynx covered in abdomen doesn't cover much details), blood supply and lymphatic drainage of head and neck, etc

Awesome experience, perfect learning tutorial ... i personally love it because it's more of a teacher to me... love it

Superb best video till now. So it is really helping me

I have watched the lecture series on the Abdominal wall and Thoracic viscera conducted by professor Craig, and he was more interactive and seemed to have greater Knowledge in those parts. This lecture is way too general and lacks many important info.

Seems a little bit robotic... is not a natural lecture... is too obvious the prompter reading

Good good good good good good good good good good

its osam and very easy to understand, visual effects are too good

Short and to the point, good professor, and good test prep questions

I am a neurosurgeon. this lecture is fantastic and very useful. i just wish if the quiz has more questions

This is one of excellent style of teaching skills and experiences. I recommend students and medical doctors who need to pass a qualifying exam to subscribe and finish all course work.

i like it because it teaches me about the regions of the neck and other things also i want to know more about the triangle of the neck

its boring lecture and the lecturer was so slow in talking i think there is deficiency in information

I chose it because it contain almost every related to topics....like question, articles and etc. Because of the smart classes all the doubts are clear....

I wish this is more about anatomy and less about diereses, as I am in this class right now for my primary objective I need to know the names of every muscles, every bones, what they do, every nerve, what they innervate, and every veins and arteries, also lymphatic and different glands in your faces the videos do not provide enough details and topics I am currently using Clinically Oriented Anatomy 7th Edition by Kieth L. Moore, comparing the knowledge from the book these videos give you almost nothing

It would be nice to have subtitles for spanish audience. Other than that everything looks great.

No such thing as the "internal" oblique. It's called the inferior oblique. Also, should state whether these are primary or secondary actions of the muscle.

I like his lecture & way of teaching. It meet my expectation.

Very good videos and imágenes, I recommended this app 100% . very well summarized

I found this very helpful. I don't mind if it's just a general review because if you cover them all it would take a long time. I can read books for more in-depth analysis. Great job !

Unfortunately, the lecturer for the anatomy module has disappointed me. Whereas the lecturers in all other modules appear to be amazing, this lecturer speaks way too slow and with a boring tone. I have to listen to the lectures in 1.5x..

The course was clear with good illustrations and clear speech,

I thought this lecture series was very simple and informative, easy to understand but thorough. I appreciate the pneumonic provided, as well as the transcript notes available So we could go back and look and write things down as needed- I Was happy that the teacher spoke clearly and slowly, and that each segment was not very long so that you were able to take time to contemplate information before moving on.

a quick video to clear the concept thank you very much

Yes. I like the details presentation all Information nicely given good language in short time

Learnt a few new things. Clear and concise. Really good lecturer. Would recommend to anyone studying anatomy.

thank you doctor Craig for this video it's very helpful i hope you make anther one about cranial nerves specially 5th and 7th

The Lecture is very good. However the image does not clearly highlight the foramen. There appears to be an overlap of Foramen Lacerum with the Internal acoustic meatus.

It was great you will never miss a thing everything clear even the diagrams

Good and clear discussions on conditions related to the neck.

The Material was presented thoroughly in a manner that was easily understood

Lecture was a bit boring, less emphasis even though content was superb.

The best lecture about this topic that I´ve seen in my life. Thank you so much, I´m enjoying the anatomy lectures!

Clear explanation and easy to understand. Good guide to learn Anatomy

monotone basic basically doesn't really explain anything it just sites things

Dr. Canby provides clear and concise discussion with regard to head and neck anatomy. This has proven to be a great secondary resource for my studies. As an M.D. student, the amount of information is vast, and these lectures provide a great supplement to my university materials. The most effective way I have found to use this material is by viewing the videos that correlate to my current coursework, completing the recall questions, and then reading through the associated articles that are provided throughout the course.

He is the best one to teach anatomy! I love his voice, his style and his presentation. He makes it more simple for the students to visualize something palpable but hidden under the skin and thousands of other components.

Its very clear and simple...Mneumonics are interesting and easy to remember

I believe that his explanation was 100% solid, clean, and straight to the point.

for more understanding of the movement of the eye it should be presented on real eye not on photos ... ty

He explains good, Easy to understand and move on. Only problem is that he doesn't cover some topics about head and neck Anatomy.

There's a lot of structure missing and the way its presented is a bit boring compared to other instructors on youtube.

I love Lecturio Anatomy lectures because everything that you see it's better and easy to learn. When I see all the names in the ATLAS I'm stressed, but then, when I watch lecturio it's easy because they explain you everything step by step not only theoretically!

so helpful,,,,, now have clear concept of many things,,,,thank you sir

lecture was excellent. cleared the concept in a few minutes. this was really helpful

Good pace, but information relating to the thyroid gland is lacking. This is more of a general overview.

Simply awesome. The delivery, speed and diction is just excellent. Its anatomy made easy

I would like in the questions, a rationale of the answer goes directly to the part of the lecture where it is explained. Like an option would be great

Lecturer is knowledgeable and seems to care about the student's understanding of the material.

Lecture covered lots of details without becoming boring. Presented at a medically relevant level. Basically, animates the contents in an anatomical atlas. Results are better retention!

Overall great, but is missing much of the details in the skull (for example names of the specific bones, features of the bones, etc.) and head in general.

A clear and concise overview of the fascial spaces. However, I think the coverage of the surgical access to the trachea was way too superficial. Details of the levels of relevant anatomical zones, and how to locate these areas in a clinical manner would've been greatly appreciated. Otherwise very useful!

Whilst useful for a brief introduction, I do not feel the lecturio anatomy programme in general provides sufficient detail to be a main-line resource. The videos are too brief and superficial in content to adequately prepare a student for internal examinations, let alone to an NBME standard. The presentation itself is clear and ok.

this is perfect explain of Triangles of the Neck thx doctor.Craig Canby

clear and concise introduction to the thyroid gland and thyroidectomy relative to the fascial spaces

great to come to this site and explore everything.it helped me a lot in my exam .its is agreat benefit to me

it is extremely general and does not provide the important notes about the gland like its blood suplly, innervation and details about what could be damaged if a thyrodectomy was preformed wrongly.

The course brings the general ideia of the anatomy content with interesting clinical correlations. Although, the lectures could be more detailed, specially in vascular anatomy. I also suggest more precise images.

Great lecturer and keeps it simple with step by step. Also his slides are very simple yet thorough thereby not confusing the student with too much content per slide.

Since anatomy is a very difficult subject and very vast, I think that Canby does an excellent job at slowing down and being concise. This lecture hits all the key points as well as ask relevant questions to help retain the information.

Great Simple Teaching. Learning the different parts of the neck is interesting.

is very good because learn things new and interesting why me amazing

It's very helpful, I was able to revise alot under a short period of time.

Amazing lecture . I really liked it and learned from it a lot . Thank you

Good videos, but incomplete for a full head and neck series - does not include important structures such as facial and trigeminal nerves, more on neck dissections - which are crucial for understanding head and neck anatomy

It is very basic and insufficiant. not enough to learn from at all.

I picked this rate because he gives detail about the neck and parts of the neck. I really like this for a 9th grader it's helping me learn more for med school. Please do more videos, not just for me, but for people that want to be something when they make it to med school or college. This website is very helpful in many ways like: when you are on the way to school and your have a test about the human body, or when you just want to study for a test a week or two away. I plan to keep using this website for important chooses in my life. I want to be able to help people with their problems and give them information. I don't want to go home and be that one person with a dream and not go for it. I want to be a help and influence to people in need so, keep making these videos and make people happy for what they want to be in life. Dezire Baker

very nicely and smoothely explained .D And the diagrams choosed very nicely and wisely
