The Adrenal Medulla

Question

The adrenal medulla
A) is controlled primarily by ACTH.
B) secretes steroids.
C) is part of the fight-or-flight response.
D) secretes iodine-containing hormones.

Accepted Answer

The adrenal medulla is part of the sympathetic nervous system and releases hormones such as adrenaline and noradrenaline during the fight-or-flight response.

Answer: D
 The adrenal gland's outer layer, the cortex, secretes steroids such as cortisol and aldosterone. The adrenal medulla does not secrete iodine-containing hormones, which are produced by the thyroid gland.

Therefore, the correct answer is C.
