WebChromaffin cells in the adrenal medulla are specialized for the synthesis, storage, and secretion of catecholamines. These cells are innervated by preganglionic sympathetic neurons in the splanchnic nerves, and, because of their unique blood supply, are exposed to unusually high concentrations of glucocorticoids in the venous drainage from the … Catecholamines are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Dopamine, which acts as a neurotransmitter in the central nervous system, is largely produced in neuronal cell bodies in two areas of the brainstem: the ventral tegmental area and the substantia nigra, the latter of which contains neuromelanin-pigmented neurons. The similarly neuromelanin-pigmented cell bodies o…
