What gland produces catecholamines?

Answer 1

"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 substantia nigra and the ventral tegmental area. The similarly melanin-pigmented cell bodies of the locus ceruleus produce norepinephrine." - Wikipedia

The main catecholamines are epinephrine and norepinephrine, which are produced in the adrenal medulla (in the adrenal glands). Dopamine is the other, which is from neuronal cell bodies.
