Innervation = 9th-12th intercostal nerves stabilize ribs against pull of diaphragm: not moving body, but causing changes at joint, get feedback in contraction fed back to nervous system. Intermediate muscles are deep: long muscles are superficial, short muscles lie against vertebrae (usually only extend to 1 vb; ex.
