All other hormones

Epinephrine

EPI adrenal medulla - about 80% Causes heart rate to increase and glucose levels in blood to increase, used in fight or flight to stimulate sympathetic nervous system

Norepinephrine

NE Adrenal medulla - about 20% Also stimulates sympathetic nervous system, control blood pressure, increase alertness.

Glucagon

Pancreas Action: stimulates the liver to break down glycogen and convert noncarbohydrates into glucose; stimulates breakdown of fats Source: blood glucose concentration Glucagon breaks down glycogen into glucose, releasing sugar

Somatostatin

SS Pancreas Action: helps regulate carbohydrates

Insulin

pancreas Action: promotes formation of glycogen from glucose, inhibits conversion of noncarbohydrates into glucose, and enhances movement of glucose through adipose and muscle cell membranes, decreasing blood glucose concentration, promotes transport of amino acids into cells, enhances synthesis of proteins and fats Source of control: blood glucose concentration Insulin forms glycogen from glucose, storing sugar

Cortisol

Adrenal Cortex - zona fasciculata Action: decreases protein synthesis, increases fatty acid release and stimulates glucose synthesis from noncarbohydrates Factors regulating: CRH from the hypothalamus and ACTH from the anterior pituitary gland

Aldosterone

Adrenal Cortex - zona glomerulosa Action - helps regulate the concentration of extracellular electrolytes by conserving sodium ions and excreting potassium ions Regulated by: electrolyte concentrations in body fluids and renin-angiotensin system

Adrenal Androgens

Adrenal Cortex - zona reticularis Action: supplement sex hormones from the gonads, may be converted into estrogens
