Question

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

Explanation:

Cushing Disease is caused by a tumor in the adenohypophysis (anterior pituitary gland) that secretes excess adrenocorticotropic hormone (ACTH), leading to increased cortisol production. The parathyroid gland is related to calcium regulation, neurohypophysis (posterior pituitary) has different hormone functions, and the thyroid is for thyroid hormone production, none of which are directly associated with Cushing Disease's primary cause.

Answer:

D. Adenohypophysis
