The ________ of the Adrenal Gland Occupies About 80 Percent

Question

The ________ of the adrenal gland occupies about 80 percent of the cortex.
A) zona fasciculata
B) chromaffin cells
C) zona reticularis
D) capsule
E) zona glomerulosa

Accepted Answer

The zona fasciculata is the middle layer of the adrenal cortex and it occupies approximately 80 percent of the cortex. It mainly produces glucocorticoids, such as cortisol. The other zones of the adrenal cortex include the zona glomerulosa (produces mineralocorticoids, such as aldosterone), and the zona reticularis (produces androgens, such as testosterone). The chromaffin cells are found in the adrenal medulla and produce catecholamines, such as epinephrine and norepinephrine. The capsule is the outermost layer of the adrenal gland.
