Regarding the functions of the posterior pituitary gland.?

Question

a.Oxytocin stimulates milk production.

b.The posterior pituitary secretes epinephrine

c.The posterior pituitary gland secretes growth hormone.

d.Vasopressin regulates the uptake of water by the cells of the collecting duct

Answer 1

b. is definitely false--the adrenal medulla secretes epinephrine

c. is definitely false--the anterior pituitary secretes growth hormone

d. is true.

a. is kind of true. Oxytocin promotes milk "let down," but not milk production by the mammary glands. Prolactin released by the anterior pituitary increases milk production. But some sources say that oxytocin "promotes lactation," which is sometimes used synonymously with milk production.

If only one answer is correct, I'd go with d. If a. and d. together are a choice, you might go with that.

Answer 2

D
