Q. Which is correct regarding the functions of posterior pituitary gland?
A) The posterior pituitary gland secretes growth hormone
B) The posterior pituitary secretes epinephrine
C) Vasopressin regulates the uptake of water by the cells of the collecting duct
D) Oxytocin stimulates milk production
Explanation
The posterior pituitary gland secretes two hormones, vasopressin (or ADH) and oxytocin. Vasopressin regulates the body’s water balance. Oxytocin plays a role in lactation by stimulating the ejection of milk from the breast in response to sucking but milk production is promoted by prolactin secreted by the anterior pituitary.
