Skeleton cinguli pectoralis sinistri · Kostra levého pletence horní končetiny
Skeleton
Looks like
The bones of the shoulder girdle, clavicle and scapula, and the joints joining them to each other and to the sternum.
What it does
Gives the arm a mobile base, letting the shoulder blade glide over the ribs to widen its reach.
Keeping it well
A winging shoulder blade suggests a nerve injury to the muscle that holds it; shoulder pain lasting weeks needs a check.
