The muscles of the shoulder bridge the transitions from the torso into the head/neck area and into the upper extremities of the arms and hands. It is also one of the greatest and most complex joints in the body. The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder bone), like a ball and socket. The shoulder has about eight muscles that attach to the scapula, humerus, and your collarbone (clavicle). These muscles form the outer shape of the shoulder and underarm. The largest of these shoulder muscles is the deltoid. This large triangular muscle covers the glenohumeral joint and gives the shoulder its rounded-off shape. It stretches across the top of the shoulder from the clavicle in the front to the scapula in the back. Let’s discuss here the anatomy of shoulder muscle in detail with the help of 3D model.
The various muscles that form the shoulder are as follows:
Deltoid: The Deltoid muscle is the largest muscle located on the outside of the shoulder. It has three major parts that control shoulder flexion (forward elevation) , shoulder abduction (outside arm elevation away from the midline of the body) and shoulder extension (movement of the arm behind the back).
Infraspinatus: The Infraspinatus is a rotator cuff muscle that controls shoulder external rotation.
Subscapularis: The Subscapularis is a rotator cuff muscle that controls shoulder internal rotation.
Supraspinatus: The Supraspinatus is a rotator cuff muscle that primarily controls shoulder abduction (outside arm elevation away from the midline of the body).
Teres Major: The Teres Major is a shoulder muscle that controls shoulder adduction.
