Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cushing’s syndrome is caused by:
A
hyposecretion of the adrenal cortex
B
hypersecretion of the adrenal cortex
C
hyposecretion of the thyroid gland
D
hypersecretion of the thyroid gland
Explanation: 

Detailed explanation-1: -Cushing’s disease is caused by endogenous hypercortisolism. This is due to the hypersecretion of the adrenocorticotropic hormone (ACTH) by an ACTH-secreting pituitary adenoma [1]. It is considered a rare condition, though it is recognized as a cause of Cushing’s syndrome [2].

Detailed explanation-2: -Abstract. Hypersecretion from the adrenal glands is associated with hypertension. Causes include Conn syndrome, Cushing syndrome and phaechromocytoma.

Detailed explanation-3: -Cushing disease is caused by a tumor or excess growth (hyperplasia) of the pituitary gland. The pituitary gland is located just below the base of the brain.

Detailed explanation-4: -Cushing’s syndrome happens when you have too many corticosteroids in your body. When the disorder often starts with the pituitary gland, the condition is called Cushing’s syndrome. The gland makes too much adrenocorticotropin hormone (ACTH). That causes the adrenal glands to make too many corticosteroids.
