Answer :
The anatomy of the shoulder includes bones, muscles, ligaments, and tendons. The structures that stabilize and move the shoulder include the rotator cuff muscles, ligaments, and labrum.
The shoulder is a complex joint that allows a wide range of motion and consists of several key anatomical structures.
Glenohumeral joint is the primary joint of the shoulder, where most of the movement occurs.
It is a ball-and-socket joint, allowing for flexion, extension, abduction, adduction, internal and external rotation, and circumduction.
The rotator cuff is a group of four muscles (supraspinatus, infraspinatus, teres minor, and subscapularis) that stabilize the shoulder joint and facilitate its movement.
