cut edge of amnion, junction region, lateral plate mesoderm, left sinus venosus, left vitelline (omphalomesenteric) vein, midgut, neural canal, neural tube, occipital neural crest, pericardioperitoneal canal (pleural cavity), right dorsal aorta, right horn of sinus venosus, right vitelline (omphalomesenteric) vein, somite 3 (O-3), umbilical vesicle cavity

A section through somite 3 and the cranial part of the midgut.

Observe:
1. The wide communication between the midgut and yolk sac cavity.
2. The junction of the umbilical and vitelline veins in Section 12 with the sinus venosus.
3. The pericardioperitoneal canal surrounded with lateral plate mesoderm.
4. The ventromedial extent of the somites below the neural tube.
