# All of the following hormones are secreted by anterior pituitary except:

 C. ADH

 D. FSH

The correct answer is C. ADH.

The anterior pituitary gland, also known as the adenohypophysis, secretes several key hormones that regulate various physiological processes. These include:

ACTH (Adrenocorticotropic Hormone): Stimulates the adrenal glands to produce cortisol, a hormone involved in stress response.

TSH (Thyroid-Stimulating Hormone): Stimulates the thyroid gland to produce thyroid hormones, which regulate metabolism.

FSH (Follicle-Stimulating Hormone): Plays a crucial role in regulating the reproductive processes, stimulating the development of follicles in ovaries and sperm production in the testes.

On the other hand, ADH (Antidiuretic Hormone), also known as vasopressin, is not produced by the anterior pituitary. 

Instead:

ADH is synthesized in the hypothalamus and stored in the posterior pituitary (neurohypophysis). Its main function is to regulate water balance in the body by controlling the kidneys' water retention, which helps maintain blood pressure and hydration.

Thus, while ACTH, TSH, and FSH are secreted by the anterior pituitary, ADH is released from the posterior pituitary.

This makes the correct answer: C. ADH.
