Sympathetic innervation of the adrenal medulla
Innervation (left) and synaptic signaling of chromaffin cells (right) in the adrenal medulla.
1 and 2: Preganglionic sympathetic fibers from the thoracic spine directly innervate the chromaffin cells, which are neuroendocrine cells similar in structure to sympathetic neurons.
3. An action potential opens a voltage-gated calcium channel.
4. The increased calcium ion concentration within the synaptic cell triggers the release of the neurotransmitter acetylcholine (ACh) from vesicles into the synaptic cleft.
5. The nicotinic ACh receptors on the chromaffin cells are ligand-gated ion channels. The influx of sodium ions triggers depolarization of the cell, which leads to the opening of voltage-gated calcium channels.
6. The increased calcium ion concentration within the chromaffin cell triggers the secretion of norepinephrine and epinephrine from the secretory granules into the bloodstream. Approx. 80% of chromaffin cells produce epinephrine, while only 20% produce norepinephrine.
7. The predominant serum catecholamine is norepinephrine (80%). This increase in serum norepinephrine occurs because norepinephrine is also secreted as a neurotransmitter by the postganglionic fibers from the sympathetic trunk, while epinephrine is produced almost exclusively by the adrenal gland.
