The adrenal gland is comprised of an outer cortex sur- ularis by increasing intracellular cAMP. Angiotensin II and angiotensin III stimulate aldosterone glomerulosa, zona fasciculata, and zona reticularis. Hormones secreted by the adrenal cortex include glucocor- ing cytosolic calcium and activating protein kinase C. The glucocorticoids cortisol and corticosterone are synthe- tosol of target cells. The glucocorticoid-bound receptor sized in the zona fasciculata and zona reticularis of the ad- translocates to the nucleus and then binds to glucocorti- renal cortex. The mineralocorticoid aldosterone is synthesized in the the transcription of specific genes. Cholesterol, used in the synthesis of the adrenal cortical to fasting, injury, and stress.
