MICROANATOMY

Detailed explanation-1: -The adrenal gland is made up of the cortex and medulla . The cortex produces steroid hormones including glucocorticoids, mineralocorticoids, and adrenal androgens, and the medulla produces the catecholamines, epinephrine, and norepinephrine.

Detailed explanation-2: -The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.

Detailed explanation-3: -The adrenal cortex produces several hormones. The most important are aldosterone (a mineralocorticoid), cortisol (a glucocorticoid), and androgens and estrogen (sex hormones).

Detailed explanation-4: -The adrenal medulla produces hormones involved in the fight-or-flight response (catecholamines, or adrenaline type hormones such as epinephrine and norepinephrine).

Detailed explanation-5: -Noradrenaline is the main neurotransmitter of the sympathetic nerves in the cardiovascular system. Adrenaline is the main hormone secreted by the adrenal medulla. The sympathetic noradrenergic system plays major roles in tonic and reflexive changes in cardiovascular tone.
