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.

Too fast
By Grzegorz W. on 18. October 2020 for Gastrulation and the Trilaminar Embryo

Too fast and sometimes lacking pretty basic, though essential details about the whole process.

Great Lecture series

Hello Professor Ward. M1 student from CA here. I just wanted to say that I think these lectures are super awesome, and thank you for taking the time for ensuring good quality while also making great responses to student questions.

I find embryology confusing and this video really helped me out, thank you

I was totally confused and feeling overwhelmed with this topic, but once I started watching the videos everything became clear. Now due to to this course and the excellent explanations, I feel ready for my embryology test.
