What is the rotator cuff anatomy? The rotator cuff is made of four shoulder muscles: The supraspinatus lets you rotate and lift your arm. It stretches from the top of your scapula to the upper end of your humerus (its head). The subscapularis lets you hold your arm outstretched, away from your body.
The rotator cuff is a group of four muscles that hold your upper arm in place in your shoulder. It helps you make all the motions of your arm and shoulder. The head of your...
In the human body, the rotator cuff is a functional anatomical unit located in the upper extremity. Its function is related to the glenohumeral joint, where the muscles of the cuff function both as the executors of the movements of the joint and the stabilization of the joint as well.
Your rotator cuff is made up of four muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis. The muscles start on the shoulder blade (scapula) and join as tendons to form a thick covering at the top of the humerus (the bone in the upper arm).
The rotator cuff is a group of muscles and their tendons that act to stabilize the human shoulder and allow for its extensive range of motion. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are: subscapularis muscle.
The Rotator Cuff (RC) is a common name for the group of 4 distinct muscles and their tendons, which provide strength and stability during motion to the shoulder complex. They are also referred to as the SITS muscle, with reference to the first letter of their names ( Supraspinatus , Infraspinatus , Teres minor , and Subscapularis , respectively).
The rotator cuff is a group of muscles in the shoulder that allow a wide range of movement while maintaining the stability of the glenohumeral joint (see Image. Rotator Cuff Muscles). The rotator cuff includes the following muscles[1][2][3]:
The primary muscle group that supports the shoulder joint is the rotator cuff muscles. The four rotator cuff muscles include the supraspinatus, infraspinatus, teres minor, and subscapularis. [2] [1] Other muscles that form the shoulder girdle include the pectoralis major, pectoralis minor, the deltoids, trapezius, and the serratus anterior.

It is a complex anatomic structure commonly affected by injury such as tendinopathy and cuff tears. The rotator cuff helps to provide a stabilising effect to the shoulder joint by compressing the humeral head against the glenoid cavity via the concavity compression mechanism.
