Human Embryo Head (Carnegie stage 11)
|
width=400px|Ventral view of the Week 4 embryo 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.
A SEM image version of this image is also available. |
Relative to the Stomodeum
- Cranial (above) lies brain bulge covered in thin layer of surface ectoderm (surface crack is processing artefact).
- Lateral (beside) lie the primordia of the first pharyngeal arch.
- Inferior (below) lies the developing heart (lower left of image), ventral body wall removed to show heart tube.
