Answer to Question 1

ANS: C
Figure 15-1 shows two groups of neurons in the pons: (1) the apneustic center and (2) the pneu-motaxic center.

Answer to Question 2

ANS: B
Under such circumstances, the DRG inspiratory neurons fail to switch off, causing prolonged inspiratory gasps interrupted by occasional expirations (apneustic breathing).
