- Describe the wind-up theory.
- What are the target organs of the hypogastric ganglion?
- a Involves repetitive noxious stimuli (c-fibers)->prolonged discharge of dorsal horn cells-> progressive ↑ in APs per stimulus->long term potentiation (LTP).

Both organized around the aortic arch.

5 True/False questions
Blocking what ganglion is indicated in painful conditions of the lower extremities and pelvic viscera and vascular insufficiency in the legs? → Superior hypogastric plexus & ganglion impar
What do the collateral ganglia accommodate? → Preganglionic fibers which do not synapse in lateral chain, but continue in visceral ramus->splanchnic nerves which end in collateral ganglia.
What are the middle cervical ganglion? → C1-C4
What are NMDA receptors important for? → In triggering wide dynamic range (WDR) neurons that are responsible for generalization of specific nociceptive info.
Where do the celiac ganglion (collateral ganglion) receive its input? → T1 or below
