Answer to Question 1

ANS: C
The pneumotaxic center controls the switch-off point of the inspiratory ramp, thus controlling inspiratory time.

Answer to Question 2

ANS: B
Instead, the medulla contains several widely dispersed respiratory-related neurons, as shown in Figure 15-1. The DRGs contain mainly inspiratory neurons, whereas the VRGs contain both in-spiratory and expiratory neurons.
