Infraspinatus

Infraspinatus

Infraspinatus is a triangular muscle which makes up the infraspinatous fossa. The main function of the infraspinatus muscle is to stabilize the shoulder joint while also helping in rotating the arm. This muscle is attached to the infraspinous fossa medially and to the facet of humerus’ greater tubercle laterally. It is separated from teres minor and teres major by infraspinatus fascia, which also covers this muscle. Read more about Infraspinatus
