"origin: nuchal ligament, spinous processes of C7 and T1 vertebrae"
"insertion: medial border of scapula at the root of the spine of scapula"
"nerve supply: dorsal scapular nerve (C4, C5)"
"arterial supply: dorsal scapular artery"
"action: adducts (retracts) and internally rotates the scapula; aids in scapular elevation"
