Which Region of the Adrenal Gland is Regulated by the Sympathetic

Question

Which region of the adrenal gland is regulated by the sympathetic nervous system?
A) adrenal medulla
B) zona fasciculata
C) zona reticularis
D) zona glomerulosa

Accepted Answer

The adrenal medulla is regulated by the sympathetic nervous system and secretes catecholamines such as epinephrine and norepinephrine in response to stress or danger. The other regions of the adrenal gland are regulated by different hormones or factors. The zona glomerulosa is regulated by the renin-angiotensin-aldosterone system, the zona fasciculata is regulated by adrenocorticotropic hormone (ACTH) from the anterior pituitary gland, and the zona reticularis is regulated by ACTH and other factors such as androgens.
