Which hormone is NOT listed among the pituitary-associated hormones in the provided material?

• A. ACTH
• B. ADH
• C. Melatonin
• D. TSH

Answer: (C)

Hormones associated with the pituitary gland are those produced by the pituitary itself (anterior and posterior lobes) or released from it as part of the hypothalamic-pituitary axis. ACTH and TSH are classic anterior pituitary hormones, guiding adrenal cortex and thyroid function, respectively. ADH is stored and released by the posterior pituitary, though it is produced in the hypothalamus and acts on the kidneys. Melatonin, on the other hand, is produced by the pineal gland and governs circadian rhythms, not the pituitary. So it stands apart from pituitary-associated hormones.
