WebStimulation of the splanchnic nerves results in the release of ACh from nerve endings in the adrenal medulla. ACh causes an increase in the permeability of the chromaffin cells to Ca2+, and thereby leads to the entry of Ca2+ into the cells. WebThe adrenal medulla is a modified sympathetic prevertebral ganglion that releases epinephrine and norepinephrine into the blood (about 4:1) in response to sympathetic stimulation. The arrangement of the sympathetic and parasympathetic nervous systems is recapitulated. The synthesis of epinephrine is described.
