Verified step by step guidance

Understand the role of the adrenal cortex: The adrenal cortex is part of the adrenal glands, which are located on top of the kidneys. It is responsible for producing steroid hormones such as cortisol, aldosterone, and androgens.

Identify the hormone responsible for stimulating the adrenal cortex: Adrenocorticotropic hormone (ACTH) is the hormone that stimulates the adrenal cortex to release its hormones. ACTH is produced by the anterior pituitary gland.

Learn about the function of ACTH: ACTH binds to receptors on the adrenal cortex, triggering the synthesis and release of cortisol and other hormones. This process is part of the body's response to stress and helps regulate metabolism, immune response, and other vital functions.

Differentiate ACTH from other hormones listed: Luteinizing hormone (LH), prolactin, and thyroid-stimulating hormone (TSH) have different roles. LH is involved in reproductive processes, prolactin in milk production, and TSH in thyroid function. None of these directly stimulate the adrenal cortex.

Review the feedback mechanism: The release of ACTH is regulated by the hypothalamus through corticotropin-releasing hormone (CRH). This is part of the hypothalamic-pituitary-adrenal (HPA) axis, which maintains homeostasis in response to stress.
