Study Notes
Early Embryogenesis: Neural Crest Cells Derivatives
- Neural crest cells are crucial for head, face, and oral cavity development
- Highly specialized
- Migrate throughout the embryo
- Form cranial nerves, peripheral nervous system, and teeth
Early Embryogenesis: Week 4
- Embryo development involves folding processes
- Key structures form:
- Stomodeum (primitive mouth)
- Buccopharyngeal membrane
- Primitive gut
- Buccopharyngeal membrane ruptures, connecting the stomodeum and gut.

Description
This quiz covers the critical role of neural crest cells in the development of the head, face, and oral cavity during early embryogenesis. It also highlights significant structures formed in week 4, such as the stomodeum and primitive gut. Test your knowledge on the migration and specialization of these cells and the key embryonic developments that occur.
