As part of the Rotator Cuff, supraspinatus helps to resist the gravitational forces which act on the shoulder joint to pull from the weight of the upper limb downward.

Dec 5, 2022 · Together with the other rotator cuff muscles, supraspinatus stabilizes the glenohumeral (shoulder) joint during the movements of the upper limb. Additionally, it assists in the abduction of …

May 5, 2023 · The supraspinatus holds the humerus in place, resisting the downward pull of gravity on the shoulder joint due to the arm’s weight. The primary antagonists of supraspinatus are …

The supraspinatus muscle performs abduction of the arm, and pulls the head of the humerus medially towards the glenoid cavity. [5] It independently prevents the head of the humerus from slipping …

Muscle anatomy of the supraspinatus includes origin, insertion, action, innervation and vascular supply. Actions include agonists and antagonists for each movement.

Jan 26, 2024 · The supraspinatus is an intrinsic muscle of the shoulder region. It is part of the rotator cuff muscle group. Attachments: Originates from the supraspinous fossa of the scapula and attaches to …

The supraspinatus muscle abducts the arm at the glenohumeral (shoulder) joint. It is one of the four rotator cuff (SITS) muscles, the other three being the infraspinatus, teres minor and subscapularis …

The key role the supraspinatus plays is to provide additional humeral head compression within the glenoid fossa to counter the humeral head superior translation (rising up) occurring with contraction …

The supraspinatus muscle plays a crucial role in shoulder mechanics, acting as the primary initiator of arm abduction and an essential stabilizer during all phases of motion.

Jul 3, 2023 · As a key player in the shoulder complex, the supraspinatus muscle primarily acts as an abductor of the shoulder joint. It initiates the initial 15 degrees of shoulder abduction, the sideways …
