Question

the disorder directly associated with cushing disease involves which one of the following glands?
thyroid
parathyroid gland
neurohypophysis
adenohypophysis

Explanation:

Cushing Disease is caused by a tumor in the adenohypophysis (anterior pituitary gland) that overproduces adrenocorticotropic hormone (ACTH), leading to excess cortisol. The thyroid is for thyroid hormones, parathyroid for calcium regulation, neurohypophysis (posterior pituitary) stores hormones, not directly involved in Cushing Disease. So the gland associated is adenohypophysis.

Answer:

D. Adenohypophysis
