The innervation of the adrenal glands is via visceral afferent fibers arising from the celiac, aorticorenal, and renal ganglia. These fibers connect with the posterior vagus nerve, phrenic nerve, and greater and lesser splanchnic nerves.
The nerve fibers provide sensory or indirect vasomotor innervation as they traverse the adrenal cortex and terminate in the medulla as preganglionic sympathetic fibers.
