The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.

What part of the rotator cuff is the most frequently injured and why?
Rotator cuff is composed of four muscles. These muscles keep the head of the humerus in proximity to the scapula bone. Any force, that tries to pull away the head of the humerus will cause injury to the rotator cuff muscles. Any body can get such injury.
What tendons and or muscles make up the rotator cuff?

What is cuff muscles?
The rotator cuff is comprised of four muscles. These individual muscles combine at the shoulder to form a thick "cuff" over this joint. The rotator cuff has the important job of stabilizing the shoulder as well as elevating and rotating the arm. Each muscle originates on the shoulder blade, or scapula, and inserts on the arm bone, or humerus.
What is a rotator cuff injury definition?
Well, your 'rotator cuff' is comprised of four muscles: Supraspinatus, Infraspinatus, Teres Minor, and Subscapularis. These four muscles encompass, and therefore stabolize, the glenohumeral joint (the joint where your arm[humerus bone] joins your shoulder blade[scapula bone]). These muscles help move your arm at the shoulder in all angles. So, if you have a 'rotator cuff tear' it is an injury or strain to one or more of these muscles.
What is mild rotator cuff tonden?
The mild rotator cuff tonden refers to the muscles that connect the shoulder blade to the upper arm.
How many muscles make up rotator cuff?
Four muscles in a persons body make up a rotator cuff: supraspinatus muscle, infraspinatus muscle, teres minor muscle and the subscapularis muscle.There are four muscles that make up a rotator cup.name the muscles please
What is a 1.5 x 1.5 cm focal rotator cuff tear?
A group of 4 muscles form the rotator cuff and help to stabilise the shoulder joint. It means that there is a tear in the rotator cuff muscles about 1.5 x 1.5 cm g. Rotator cuff injuries causes difficulty in lifting your arm and may require surgical intervention
What is a rotator cuff?
The rotator cuff is a group of tendons and their related muscles that helps keep the upper arm bone securely placed, or seated, into the socket of the shoulder blade. Rotator cuff disorders are usually caused by a combination of factors, such as normal wear and tear. Age-related degeneration slowly damages the rotator cuff, causing one or more tendons to rub against the bones (impingement). Partial or complete tears to the rotator cuff tendon are more likely to occur when the rotator cuff is already scarred, weakened, or damaged. A complete rotator cuff tear in a person with an otherwise healthy shoulder is most often caused by an extremely forceful injury. PAINPAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What are the function of the muscles in the rotator cuff?
The rotator cuff is a collection of muscles that act on the glenohumeral joint (shoulder joint) which are used to rotate the arm. There are four muscles in the rotator cuff called Supraspinatus, Infraspinatus, Teres Minor and Subscapularis.
What muscles form the rotator cuff?
subscapularis, supraspinatus, infraspinatus and teres minor
Why would a dislocated shoulder also potentially result in injury to the rotator cuff?
Rotator Cuff Muscles (SITS) Supraspinatus Infraspinatus Teres Minor Subscapularis Rotator cuff muscles all attach to the head of the humerus and act to seat the head of the humerus firmly in the glenoid fossa to prevent shoulder dislocation. A dislocated shoulder means some/all of these muscles have been torn.
Where is the rotator cuff located?
It is the bone at the top of your shoulder. Where the arm meets the torso. To be a little more specific, the rotator cuff is not a bone, but actually four muscles (the Teres Minor, the Infraspinatus, the Supraspinatus and the Subscapularis if you want to know specifics) that get their name because they help rotate the arm and provide stability for the shoulder. !
