Third Week Embryology: Gastrulation and Notochord Formation

This lecture focuses on the developmental milestones of the third week, including gastrulation and its processes, primitive streak formation, notochord development, and trophoblast growth. We will explore the formation of key anatomical structures such as the oropharyngeal membrane and axial development while emphasizing their roles in embryonic progression. Through detailed analysis of gastrulation's mechanisms, including epithelial-mesenchymal transition, the lecture highlights fundamental...
