Question 6 The rotator cuff muscle that medially rotates the arm is the: Subscapularis Supraspinatus Infraspinatus Teres minor

The rotator cuff muscle that medially rotates the arm is the **Subscapularis**. Here's a brief explanation of each muscle's function: 1. **Subscapularis**: This muscle is located on the anterior (front) side of the scapula and is primarily responsible for medially rotating the arm. 2. **Supraspinatus**: This muscle is located above the spine of the scapula and is primarily responsible for abducting the arm (lifting it away from the body). 3. **Infraspinatus**: This muscle is located below the spine of the scapula and is primarily responsible for laterally rotating the arm. 4. **Teres Minor**: This muscle is also involved in lateral rotation of the arm. Thus, the correct answer is **Subscapularis**.
