Epinephrine and norepinephrine can cross the synapse act as neurotransmitters but may also be released into the bloodstream by adrenal medulla (catecholamine) For those who do not produce their own insulin: various cortical steroids (prednisone, prednisolone, cortisone etc) are commonly prescribed for inflammation of many types. Sex sterioids: progesterone, estrogen and androgens, insulin, thyroid hormones (t3 and t4, glucocorticoids (cortisol) Endocrine glands produce endocrine hormones stimulated by drugs: pituitary gland, hypothalamus, thyroid gland beneath thyroid cartilage of larynx, parathyroid gland, adrenal glands sitting on top of kidneys, pancreas, testes/ovaries, placenta produces sex steroids during pregnancy temporary. Maintains uterine lining so it can continue to grow.
