INFERIOR MESENTERIC GANGLION

 

DESCRIPTION: The ganglion is placed at the origin of the inferior mesenteric artery, close to the inferior mesenteric plexus. It receives preganglionic sympathetic fibers from the lumbar splanchnic nerves, which relay in the ganglion. Their postganglionic fibers are distributed with the branches of the inferior mesenteric plexus.

BRANCHES:

bullet

Branches to secondary plexus as enumerated above

bullet

Left colic secondary plexus (descending colon)

bullet

Sigmoid plexus (sigmoid colon)

bullet

Superior rectal plexus (rectum)

FUNCTIONAL COMPONENTS:

bullet

GVE sympathetic vasomotor fibers from roots L1-3.

bullet

GVA fibers for sensory sympathetic nerves.

ROOT: The vasomotor sympathetic fibers originate from the ventral part of the intermediolateral horn of L1-3 spinal cord segments. Also the dorsal part of the intermediolateral horn provides the pseudounipolar sensory neurons whose cell bodies lie in the spinal ganglia L1-3.
