Question

All these can cause Cushing syndrome except?

1) ACTH hypersecretion by the pituitary.
2) ACTH-secreting tumors.
3) hyperactivity of the adrenal cortex.
4) hyperactivity of the adrenal medulla.
5) excess cortisol secretion.

Answer 1

Cushing syndrome, also known as Cushing's syndrome, is a disorder caused by the hypersecretion of the glucocorticoid hormone cortisol. The condition can be caused by ACTH hypersecretion by the pituitary, ACTH-secreting tumors, hyperactivity of the adrenal cortex, and excess cortisol secretion. The proper functioning of the adrenal medulla does not typically result in Cushing syndrome.

Step-by-step explanation:

Cushing syndrome, also known as Cushing's syndrome, is a disorder caused by the hypersecretion of the glucocorticoid hormone cortisol. It can result from various factors such as ACTH hypersecretion by the pituitary, ACTH-secreting tumors, hyperactivity of the adrenal cortex, and excess cortisol secretion. However, hyperactivity of the adrenal medulla does not typically cause Cushing syndrome.
