Pars tuberalis
3

Vasopressin (ADH) is stored and released by the neurohypophysis (pars nervosa) of the posterior pituitary.

Which of the following statements about growth hormone (GH) is correct?

GH is secreted by the posterior pituitary.
GH promotes protein synthesis and cell growth.
GH decreases blood glucose levels.
GH deficiency leads to acromegaly.
2

GH is secreted by the anterior pituitary and promotes protein synthesis and cell growth.

Which of the following hormones is secreted by the placenta during pregnancy?

Insulin
Human chorionic gonadotropin (hCG)

Which hormone is known as the "stress hormone"?

Epinephrine
Cortisol
Insulin
Glucagon

Which hormone regulates calcium levels by inhibiting bone resorption?

Parathyroid Hormone (PTH)
Calcitonin
Thyroxine
Aldosterone
2

Calcitonin, secreted by the thyroid gland, lowers blood calcium levels by inhibiting bone resorption.

Which hormone, secreted by the posterior pituitary, plays a role in kidney water retention?

Oxytocin
Vasopressin
Aldosterone
Erythropoietin
2
