Supraspinatus – Functional Anatomy


Supraspinatus is a rotator cuff muscle located on the superior aspect of the scapula.

Origin: Supraspinous fossa

Insertion: greater tubercle of the humerus

Function: abduction of the humerus. Details vary from one study to another but it appears to pull the humerus into the fossa as it abducts and resists downward glide of the humerus in the fossa.
