AC Brown page 1 A6l-a INTRODUCTION A. Functional Anatomy 1. Two glands: adrenal cortex and adrenal medulla 2. Located on the superior pole of the kidneys B. Hormones 1. Adrenal cortex: steroid hormones (synthesized from cholesterol) a. glucocorticoids (e.g. cortisol); named for their effects on carbohydrate metabolism but note they have many other effects b. mineralocorticoids (e.g. aldosterone); named for their effect on mineral (Na, Cl, and K) excretion by the kidneys c. sex hormones (e.g. testosterone); normally relatively low output compared to the male testes 2. Adrenal medulla: catecholamines a. epinephrine (adrenalin) b. norepinephrine (noradrenalin) Note: Mineralocorticoid actions covered with the kidney; Sex hormone action covered with the reproductive system; Adrenal medulla hormone action covered with the autonomic nervous system, so these notes will concentrate on adrenal cortex glucocorticoids
