Match the following muscles to their effect on breathing

• Quiet inspiration

• None

• Active expiration

• - Diaphragm

  - External intercostals

• Active inspiration

• - Abdominals

  - Internal intercostals

• Quiet expiration

• - Scalenes

  - Sternocleidomastoids

SATA: Which of the following are true regarding DRG?

• Inspiratory and expiratory neurons during active breathing.

• The pacemaker

• Inspiratory neurons.

• Controls the diaphragm and causes quiet inspirations.

SATA: Which of the following are true regarding the VRG?

• ONLY controls inspiratory neurons

• controls Inspiratory and expiratory neurons during active breathing.

• Controls the diaphragm during quiet inspiration

• Controls the muscles needed for active inspiration and active expiration.

SATA: What are the functions of the Pre-Botzinger complex?

• Drives the rate of DRG firing

• Acts as the Pacemaker that sets the basal respiratory rhythm.

• Communicates with the DRG

• Communicates with the VRG

What is the role of the Pneumatic center?

• Switch on the DRG for smooth I/E transition.

• Switch off the DRG for smooth I/E transition.

• Regulates inspiratory neurons of the VRG and DRG from turning off.

• Regulates the Pre-Botzinger complex.
