Physics Ch. 14 Notes 1

Front 1

Main respiratory center of the brain:

Back 1

Medullary respiratory Center

Front 2

Mainly inspiratory neurons are located bilaterally in the:

Back 2

Dorsal respiratory groups
(DRG)

Front 3

The vagus and glossopharyngeal nerves transmit many Sensory impulses to:

Back 3

Dorsal respiratory groups

Front 4

the ____ _____ _____ are located bilaterally to the medulla and contain both inspiratory and expiratory neurons.

Back 4

Ventral respiratory groups

Front 5

VRG and neurons with expiratory discharge patterns send impulses to the:

Back 5

Internal intercostal and abdominal expiratory muscles

Front 6

The inspiratory muscles receive neurons from the DRG and VRG in the form of a:

Back 6

Ramp signal

Front 7

During quiet breathing inspiratory neurons fire with increasing frequency for approximately ___ seconds and then abruptly switch off allowing for expiration to proceed for approximately ___ seconds:

Back 7

2 (inspiration)
3 (expiration)

Front 8

______ takes over control of breathing, when the main system is not working.

Back 8

Apneustic center

Front 9

The bilateral group of neurons located in the upper pons that controls the switch off point in the inspiratory ramp:

Back 9

pneumotaxic center

Front 10

The pneumotaxic center's main job is to:

Back 10

Stop inspiration
