Muscles of the Right Shoulder and Upper Arm

Illustration Description

This illustration in pencil is of the shoulder joint and depicts the muscles at anterior view forming the shoulder and upper arm. The shoulder joint, also known as the glenohumeral joint, is a ball and socket joint with the most extensive range of motion in the human body.

The muscles involved are called the rotator cuff muscles and are a collection of muscles and tendons that surround the shoulder, giving it support and allowing a wide range of motion. The four rotator cuff muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis.
