The infraspinatus located medially in the infraspinous fossa of the posterior aspect of the scapula and occupying three quarters of the infraspinous fossa. The infraspinatus is partly …
Supraspinatus Action The Supraspinatus muscle helps to initiate the abduction of the arm before the Deltoid muscle takes over. The supraspinatus also supports the head of the humerus against the glenoid cavity and therefore gives the joint stability during movement caused by actions of other muscles such as the deltoid. Supraspinatus Origin and Insertion …
