Questions and Answers
What forms the neural tube and axial skeleton?
When does the diverticular organ (allantois) form?
What is the epiblast responsible for?
Study Notes
- The embryo begins as an epiblast that migrates toward a primitive streak.
- FGF8 is responsible for controlling cell migration and specification.
- The notochord and prechordal cells form the notochordal plate and extend cranially and caudally to the primitive pit.
- The neural tube and axial skeleton are based on the notochord and prechordal cells.
- The cloacal membrane forms at the caudal end of the embryo.
- The diverticular organ (allantois) forms when the cloacal membrane appears.
