A section through the T-2 spinal ganglion, suprarenal gland and gastroduodenal junction.
Observe:
1. A ramus communicans connecting the sympathetic trunk with a ventral primary ramus.
2. The splenic primordium in the dorsal mesogastrium.
3. The lesser sac communicating through the epiploic foramen with the greater sac.
4. The portal vein, bile duct and hepatic artery ventral to the epiploic foramen.
5. The junction of the ductus venosus and umbilical vein at the liver surface.
