Question

hypothalamic - releasing hormones directly control which gland?
multiple choice
anterior pituitary gland
posterior pituitary gland
thymus
adrenal gland
kidney

Explanation:

Hypothalamic - releasing hormones are transported through the hypophyseal portal system to the anterior pituitary gland. They regulate the secretion of hormones from the anterior pituitary. The posterior pituitary stores hormones (oxytocin and vasopressin) produced by the hypothalamus but does not receive releasing hormones in the same regulatory way. The thymus is involved in immune cell development, the adrenal gland is regulated by the anterior pituitary (via ACTH) and other factors, and the kidney has its own regulatory mechanisms (e.g., renin - angiotensin - aldosterone system) not directly controlled by hypothalamic - releasing hormones.

Answer:

Anterior pituitary gland
