Detail the anatomy of the rotator cuff muscles and explain how specific yoga asanas can either support or strain these muscles.

The rotator cuff is a group of four muscles that surround the shoulder joint, providing stability and enabling a wide range of motion. These muscles, along with their tendons, play a critical role in shoulder function and are vulnerable to injury if not properly understood and cared for, especially during yoga practice. The four muscles that make up the rotator cuff are the supraspinatus, infraspinatus, teres minor, and subscapularis. The supraspinatus muscle is located on the top of the shoulder blade (scapula) and runs over the shoulder joint. Its main function is to abduct the arm, meaning to move it away from the body. It is the most frequently injured of the rotator cuff muscles, often due to repetitive overhead movements or impingement in the subacromial space where the tendons pass. The infraspinatus muscle is situated on the back of the scapula, below the supraspinatus. It is primarily responsible for external rotation of the arm, turning the arm away from the body. It also assists in stabilizing the shoulder joint. The teres minor muscle is also located on the back of the scapula, just below the infraspinatus. It works closely with the infraspinatus in externally rotating the arm and stabilizing the shoulder joint. Because of its location and close relationship to the infraspinatus, it often is injured along with this muscle. The subscapularis muscle is the only rotator cuff muscle located on the front of the scapula. Its main function is....
