Explore a comprehensive 34-minute lecture on embryology focusing on neurulation, vesiculation, and neural crest cell migration. Delve into the intricate processes of embryonic development during week 3, starting with a detailed breakdown of neurulation steps. Understand the formation of key structures such as the neural plate, neural folds, neural groove, and neural tube through clear explanations and illustrations. Progress to the vesiculation process and its significance in embryonic development. Conclude with an in-depth look at neural crest cell migration and spinal cord development. Gain valuable insights into these crucial stages of embryogenesis through Professor Zach Murphy's informative and engaging teaching style.
