The infraspinatus muscle is part of the rotator cuff muscles in the shoulder, assisting in lateral rotation of the arm.


Explanation:

The infraspinatus muscle is part of the rotator cuff muscles in the shoulder. Together with the other rotator cuff muscles (supraspinatus, teres minor, subscapularis), it plays a crucial role in stabilizing and controlling the movement of the arm.

These muscles connect the scapula to the humerus, forming a musculotendinous cuff that encircles the shoulder joint. The infraspinatus muscle, located below the spine of the scapula, assists in lateral rotation of the arm.
