Human Embryo Carnegie stage 11

Cranial neuropore (cephalic, rostral or anterior) is the initial "head end" or brain end opening of the neural tube before it closes (humans approximately 24 days post-fertilization). The pore closes within a few hours; closure is bidirectional, it takes place from the dorsal and terminal lips and may occur in several areas simultaneously. The two lips, however, behave differently.
