Case

Your challenge is to trace the sympathetic nerve supply to the enteric neurons of the stomach back to the spinal cord.

Case Complete

















- Post-ganglionic fibers
- Celiac ganglion
- Greater splanchnic nerve
- Sympathetic ganglion (chain)
- White rami communicans
- Spinal nerve proper
- Ventral roots
- Lateral horn of the spinal cord

This is the pathway for the sympathetic organ supply to all foregut organs. The parasympathetic supply arises from the vagus nerve.

Many organs are supplied by 'splanchnic' nerves. Splanchnic only refers to the nerve being 'organ directed', it does not imply anything about pre/post-synaptic identity of the nerve. In this case, the greater splanchnic is a preganglionic nerve, while in contrast the cardiopulmonary splanchnics are postganglionic nerves.
