I. Adrenocortical secretion is controlled primarily by ACTH, from the anterior pituitary, but mineralocorticoid secretion is also subject to independent control by circulating factors.

II. Adrenal medullary hormones work mostly to prepare the body for emergencies, the so-called “fight-or-flight” responses.

III. All three cortical zones secrete corticosterone, but the active enzymatic mechanism for aldosterone biosynthesis is not limited to the zona glomerulosa.

IV. An important function of the zona glomerulosa, in addition to aldosterone synthesis, is the formation of new cortical cells.
