|
Definition
SCM Traps Abs Internal/External Intercostals |
|
|
Term
What muscles are used for normal expiration? |
|
Definition
None. it's passive elastic recoil. |
|
|
Term
What three muscle groups are responsible for FORCED expiration? |
|
Definition
Internal intercostals Rectus Abdominis Transvers Abs |
|
|
Term
What do the elastic cells in the alveoli provide/what is their function? |
|
Definition
Passive elastic recoil for expiration. |
|
|
Term
Why are ab muscles important to respiration? |
|
Definition
Because they provide counterpressure to the diaphragm expansion, so the ribcage will expand rather than compression of the abdominal contents (ie: quad gut). |
