Answer to Question 1

ANS: D
Proprioceptors in muscles, tendons, and joints, as well as pain receptors in muscles and skin, send stimulatory signals to the medullary respiratory center. Such stimuli increase medullary inspirato-ry activity and cause hyperpnea. For this reason, moving the limbs, slapping or splashing cold water on the skin, and other painful stimuli stimulate ventilation in patients with respiratory de-pression.

Answer to Question 2

ANS: A
Hypercapnia, acidemia, and hypoxemia stimulate specialized nerve structures called chemore-ceptors.
