Which muscle primarily assists with shoulder abduction?

Infraspinatus
Supraspinatus
Subscapularis
Teres Minor

The correct answer is: Supraspinatus

The muscle that primarily assists with shoulder abduction is the supraspinatus. This muscle is part of the rotator cuff and is located at the top of the shoulder. Its primary function is to initiate the movement of the arm away from the body, specifically in the first 15 degrees of shoulder abduction before the deltoid takes over for the remainder of the movement. The supraspinatus plays a crucial role in stabilizing the shoulder joint while allowing for fluid movement during abduction. Its unique positioning allows it to overcome the downward pull of gravity, making it essential for elevating the arm. Understanding the function of the supraspinatus is important for recognizing how shoulder movements work collectively and can help in rehabilitation and strength training programs focused on shoulder function.
