How does the skeletal muscles tie in with respiratory system?!


Question: How does the skeletal muscles tie in with respiratory system!?
Answers:
When you inhale, your intercostal muscles expand your chest cavity!. Since nature abhors a vacuum (sorry, couldn't resist) air rushes in to fill the space!. I don't believe these are considered skeletal muscles!.

When you exhale, your diaphragm (also not a skeletal muscle) is involved, but so are your abdominals: Rectus Abdominis, Transversus Abdominis and your external and internal oblique muscles!. These are skeletal muscles (though I'm not 100% sure about the Transversus Abdominis)!.

Other muscles serve as accessory muscles in breathing!. Opinion varies as to exactly which muscles are involved but the Sternocleidomastoid and scalene muscles of the neck are generally considered accessory muscles (watch someone having an asthma attack and you'll see these muscles straining)!.

The serratus anterior, pectoralis major & minor, upper trapezius, latissimus dorsi, erector spinae (thoracic), iliocostalis lumborum, quadratus lumborum, serratus posterior superior and inferior, levatores costarum, transversus thoracis and subclavius may also have some degree of greater or lesser involvement!.
