The answer is the first one: the anterior pituitary (adenohypophysis).

Explanation for each option:

  1. Anterior pituitary (adenohypophysis): Correct. Thyrotropin-releasing hormone (TRH) is produced by the hypothalamus and targets the anterior pituitary gland. TRH stimulates the anterior pituitary to release thyroid-stimulating hormone (TSH), which in turn stimulates the thyroid gland to produce thyroid hormones.

  2. Posterior pituitary (neurohypophysis): Incorrect. The posterior pituitary does not respond to TRH. It primarily releases oxytocin and vasopressin (antidiuretic hormone, ADH), which are produced in the hypothalamus and stored in the posterior pituitary.

  3. Thyroid gland: Incorrect. The thyroid gland is the target of thyroid-stimulating hormone (TSH), not TRH. TRH acts on the anterior pituitary to release TSH, which then acts on the thyroid gland.

  4. Hypothalamus: Incorrect. The hypothalamus is the source of TRH, not its target. TRH is produced in the hypothalamus and then travels to the anterior pituitary to exert its effects.

Summary: Thyrotropin-releasing hormone (TRH) targets the anterior pituitary (adenohypophysis).
