The subscapularis muscle serves which role in shoulder movement?

External rotation of the shoulder
Internal rotation of the shoulder
Shoulder abduction
Shoulder extension

The correct answer is: Internal rotation of the shoulder

The subscapularis muscle is crucial in shoulder movement, specifically for internal rotation. This muscle is one of the four rotator cuff muscles and is located on the anterior surface of the scapula. When the subscapularis contracts, it pulls the humerus closer to the body while simultaneously rotating it inward, facilitating internal rotation of the shoulder joint. Understanding the functions of the subscapularis is essential for recognizing how it contributes to shoulder mechanics. Internal rotation is vital in various activities, particularly those that require reaching across the body or lifting objects. The muscle’s ability to stabilize the shoulder joint while allowing for this rotation helps prevent injuries and enhances overall upper body performance during exercises and daily activities.
