Answer 2

pre-botzinger complex in the medulla

Question 3

apnea is the absence of

Answer 3

inhalation

Question 4

apneusis is the absence of

Answer 4

the transition between inspiration and expiration - results from loss of pneumotaxic center

Question 5

respiratory center that generates core rhythm

Answer 5

pre-botzinger of medulla

Question 6

respiratory center that modifies inspiratory timing by turning of inspiration

Answer 6

pneumotaxic (pontine respiratory group)

Question 7

respiratory center that controls depth of breathing (tidal volume)

Answer 7

dorsal respiratory group of the medulla

Question 8

respiratory center that controls inspiration, expiration, depth

Answer 8

ventral respiratory group of medulla

Answer 9

pneumotaxic center (pontine respiratory group)

Question 10

the ventral respiratory group controls

Answer 10

modification of breathing in exercise and stress

Question 11

dorsal respiratory group controls

Answer 11

basic rhythm by triggering inspiratory impulses
