Locus ceruleus integrates the autonomic nervous system into the central nervous system for activation by the hypothalamus also synthesizes norepinephrine. Zona glomerulosa outermost layer of the adrenal cortex which produces mainly aldosterone. Zona fasciculata middle layer of the adrenal cortex which produces primarily cortisol. Zona reticularis inner most layer of the adrenal cortex which produces the gonadocorticoids (dhea and dhea-sulphate) which are considered weak androgens. Adrenal medulla middle of the adrenal gland. This is made up of chromaffins cells also called pheochromocytes. Secretes mostly epinephrine and a minor amount of norepinephrine.
