Human Embryo Buccopharyngeal Membrane (Carnegie stage 11)

This is a detailed ventral view of the Week 4 Stage 11 head, showing the stomodeum (stomatodeum or stomatodaeum) region with the floor of this region occupied by the degenerating buccopharyngeal membrane. Loss of buccopharyngeal membrane opens the gastrointestinal and respiratory tract to amniotic fluid for the remainder of development.

Scale bar 100 µm.

Facts: Week 4, 25 days, 20 somite pairs. View: This is a scanning EM ventrolateral view of the embryo head. Features: first pharyngeal arch, buccopharyngeal membrane
