Insulin is made in the beta cells of the pancreas in response to ATP from glucose metabolism. Insulin inhibits glucagon release by alpha cells of the pancreas in a negative feedback mechanism to maintain constant blood glucose levels.

Insulin has several anabolic effects, including increased glucose transport in skeletal muscle and adipose tissue, increased glycogen synthesis and storage, increased triglyceride storage, increased protein synthesis in muscles, and increased cellular uptake of potassium and amino acids.

Glycogen is made by pancreatic alpha cells and is secreted in response to hypoglycemia, resulting in glycogenolysis and gluconeogenesis to increase circulating blood glucose levels.

Chromaffin cells are found in the adrenal medulla (adrenal glands are located above the kidneys.) Chromaffin cells are regulated by preganglionic sympathetic fibers and release catecholamines, epinephrine (adrenaline) and norepinephrine (noradrenaline) into systemic circulation. The secreted epinephrine and norepinephrine play an important role in the "fight or flight" response elicited by the sympathetic nervous system. The zona glomerulosa is responsible for secreting aldosterone, the zona fasciculata is responsible for secreting cortisol (and a small amount of androgens) and the zona reticularis is primarily responsible for secreting androgens.

Epinephrine is a tyrosine derivative hormone that is synthesized in the adrenal gland. The adrenal gland has two sections: the cortex and the medulla. While the cortex secretes cortisol, aldosterone, and other glucocorticoids, the medulla secretes epinephrine and norepinephrine.

The testes are associated with testosterone production. The pituitary gland secretes several hormones that regulate numerous processes throughout the body. Adrenocorticotropic hormone (ACTH) is linked to mediation of epinephrine production, but it is the sympathetic nervous system that is responsible for stimulating epinephrine release.

Antidiuretic hormone (ADH) is a hormone that is produced in the hypothalamus and travels down nerve ending from the hypothalamus to be released from the posterior pituitary (neurohypophysis). ADH is the hormone that is responsible for reabsorbing water back into the blood stream at the level of the kidney.

The adrenal medulla is a specialized ganglion of the sympathetic nervous system. The adrenal medulla's preganglionic fibers synapse directly onto chromaffin cells located within the adrenal medulla. This causes the chromaffin cells to secrete epinephrine (80%) and norepinephrine (20%) into the circulation.

A Pheochromocytoma is a tumor of the adrenal medulla that secretes excessive amounts of catecholamines.
