Question

Which hormone is stored and secreted by the hypothalamus?

Answers

  1. Prolactin
    • Rationale:

      Prolactin is stored and secreted by the anterior pituitary gland, not the hypothalamus.

  2. Melatonin
    • Rationale:

      Melatonin is stored and secreted by the pineal gland, not the hypothalamus.

  3. Thyroxine
    • Rationale:

      Thyroxine is stored and secreted by the thyroid, not the hypothalamus.

  4. Dopamine
    • Rationale:

      Dopamine is a hormone that is secreted by the hypothalamus. It is specifically classified as a neurohormone. Its action is that of an inhibitor of prolactin from the anterior lobe of the pituitary gland.
