The adrenal cortex is the outer part of the adrenal gland, while the inner part is the adrenal medulla.

The adrenal medulla has tissues that are composed of popstganglionic sympathetic nervous system neurons which are involved in stimulating the medulla to secrete the epinephrine and norepinephrine hormones.

Epinephrine functions to increase cardiac output and increase level of glucose in the blood when the body is exposed to threat or stress.
