Prepare for embryology questions in the USMLE!

Embryology is more than observing how an egg turns into an adult. But what exactly does this important medical field entail? This question and others will be answered in this introductory course on embryology. As you will see, studying the processes of fertilization and beyond reveals many important facts apart from the embryo itself. Find out how adult diseases such as cancer develop and learn more about the characteristics and diagnosis of inherited diseases in this comprehensive online course.

This course will give you a thorough introduction to embryology and thus cover the following topics:
  • Fertilisation and the first weeks 
  • Folding and neurolation 
  • Development and abnormalities of various organs 
Yet, your studying does not pay off without constant repetition. Apply your new embryological knowledge with our set of USMLE-style questions! Designed for medical students, our question sets cover a wide range of topics and include the corresponding detailed explanations and diagrams. Combined, the lectures and the questions will help you shine in your exams!

I give a 4-star rating because it gives a general overview of the topic, giving room to build up a more comprehensive presentation.

Bad teacher and Low content
By Matheus J. on 07. January 2017 for System-Specific Embryology

The reason I gave this course a rating of 2 - is because the concepts are not explained very well, and as a result they are not conducive to understanding this science.
