During GAS alarm stage, ACTH is released by which gland?

Explanation:
The gland releasing ACTH during the alarm stage is the anterior pituitary. In the stress response, the hypothalamus first releases corticotropin-releasing hormone (CRH), which stimulates the anterior pituitary to secrete ACTH. ACTH then travels to the adrenal cortex, triggering the production of cortisol to help mobilize energy and support the stress response. The adrenal medulla releases catecholamines, and the hypothalamus releases CRH, not ACTH, so those aren’t the source of ACTH.
