Question

Quizplus · Accepted Answer

Cushing syndrome results from excess cortisol secretion, which can occur due to conditions such as ACTH hypersecretion by the pituitary, ACTH-secreting tumors, or hyperactivity of the adrenal cortex. Hyperactivity of the adrenal medulla does not cause Cushing syndrome as it is responsible for the secretion of catecholamines (epinephrine and norepinephrine) and not cortisol.
