Answer to Question 1
A
Feedback:
The hypothalamus is the coordinating center for the nervous and endocrine responses to internal and external stimuli. The pituitary, thyroid, and parathyroid glands all play an important role in maintaining homeostasis, but they do not connect the nervous and endocrine systems.
Answer to Question 2
B
Feedback:
Decongestants cause local vasoconstriction that decreases blood flow to irritated and dilated capillaries of the mucous membranes lining the nasal passages and sinus cavities. This vasoconstriction leads to a shrinking of swollen membranes and opens clogged nasal passages promoting drainage of secretions and improved air flow. Antitussives either work directly on the medullary cough center of the brain or act as a local anesthetic on the respiratory passages blocking the effectiveness of the stretch receptors that stimulate a cough reflex. Expectorants liquefy lower respiratory tract secretions, reducing the viscosity of the secretions and so making it easier to cough them up. Mucolytics break down mucus to aid a person in coughing up thick tenacious secretions by separating cells that hold mucous material together.
