caudal edge of somite 7 (C-3), cut edge of amnion, cut edge of umbilical vesicle, lateral body fold, left dorsal aorta, left umbilical vein, midgut, neural canal, umbilical vesicle cavity

A section through somite 7.

Observe:
1. The lateral body fold that narrows the communication between the midgut and the yolk sac cavity.
2. The dorsal aorta adjacent to the roof of the midgut on each side.
3. The neural canal that will become the central canal of the spinal cord.
