Answer to Question 1

C
Feedback:
The posterior pituitary stores two hormones produced in the hypothalamus: antidiuretic hormone (ADH, also known as vasopressin) and oxytocin. The posterior pituitary is anatomically an extension of the hypothalamus and is composed mainly of nerve fibers. Although it does not manufacture any hormones itself, it stores and releases hormones synthesized in the hypothalamus. The hypothalamus of the brain and the pituitary gland interact together to control most metabolic functions of the body and to maintain homeostasis.

Salmeterol (Serevent) and formoterol (Foradil) and are long-acting beta2-adrenergic agonists used only for prophylaxis of acute bronchoconstriction . Options A, C, and D are all short-acting beta2-adrenergic agonists and not used for prophylaxis.
