Answer
The adrenal medulla can be thought of as a large sympathetic (ANS) ganglion of postsympathetic neurons --minus axons and dendrites. Preganglionic fibers penetrate the adrenal cortex and synapse with the medullary neurons. The adrenal medulla and the sympathetic arm of the ANS are essentially part of a single system
Work Step by Step
The adrenal medulla synthesizes and releases catecholamine hormones/neurotransmitters. The main ones are epinephrine, norepinephrine and dopamine ( small amount).
