All of the Following are Regions of the Adrenal Cortex

Question

All of the following are regions of the adrenal cortex EXCEPT ________.
A) zona medulla
B) zona fasciculata
C) zona glomerulosa
D) zona reticularis

Accepted Answer

The adrenal cortex has three distinct regions: the zona glomerulosa, which produces mineralocorticoids such as aldosterone; the zona fasciculata, which produces glucocorticoids such as cortisol; and the zona reticularis, which produces androgens such as testosterone. There is no region called the zona medulla in the adrenal cortex. The medulla is a separate part of the adrenal gland that produces catecholamines such as epinephrine and norepinephrine.
