Early Development and the Organogenic Period

by Peter Ward, PhD

This course follows how a single-celled organism called a zygote passes through several developmental stages and creates a series of germ cell layers that will be transformed to create every type of tissue within the human body.

After completion of this course, you will be able to outline how a single-celled zygote transitions into the morula, blastocyst, bilaminar embryo, and trilaminar embryo and how the three germ cell layers (ectoderm, mesoderm, and endoderm) subdivide and create distinctive tissues throughout the body. Furthermore, you will identify various clinical or pathologic conditions can arise during these processes.

This course is directed toward health science and medical students. Any student studying embryology as part of their education will find these videos helpful.

Peter Ward, PhD

Peter J. Ward, Ph.D. has been teaching embryology, anatomy, histology, and neuroscience since 2005. He attended Carnegie Mellon University and later earned a Ph.D. in medical anatomy education from Purdue University. Dr. Ward enjoys finding ways to simplify the complex processes involved in human development and highlights the clinically-important aspects of embryology. Throughout these lectures, Dr. Ward shows how embryonic structures morph into the mature organs and other structures of the human body.

review of Peter Ward and embryology lectures
By moose h. on 21. March 2019 for Ectoderm Derivatives and Neurulation

This video, with the previous two videos are amazing. Taking embryology in med school was like greek or hebrew. Your teaching style is very helpful to dissect the processes into understandable segments. Our professor taught by day of development so there was lots of jumping around. I like the discussion of one layer from flat layer to cells to folding, to closure, etc. Very well done. Moose Henderson, PhD

not satisfied

he is too fast and diagrams used in this lectures are different and we cant imagine and is tough to understand. i saw the YouTube several times to understand what he is saying

Too fast I can not understand and imagine. Youtube animations are better.

Good Lecture yet a little awkward body language

This series of lectures saved me days of studying in my exam period in 1st semester of medschool :)
