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.

∙ 11y agoThe function of the rotator cuff muscles are simply to rotate the arm medially(inwards), to assist the deltoid in abduction(lifting of the arm), and for adduction(lowering) of the arm. The rotator cuff are also known as the SITTS muscles. Supraspinatus, located closest to the front of your shoulder, Infraspinatus, right behind it, Teres Minor right behind and slightly lower, and finally Teres Major, the large muscles that connects just beneath you shoulder and to you humerus.

What tendons and or muscles make up the rotator cuff?
what muscles make up the rotator cuff
What is mild rotator cuff tonden?
The mild rotator cuff tonden refers to the muscles that connect the shoulder blade to the upper arm.
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.
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 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 muscle agonists antagonists and assisters are involved in shoulder extension and flexion?
The muscles located in the shoulder and move the arm are: the deltoid, teres major, and rotator cuff muscles. The deltoid muscle is like three muscles in one: the anterior fibers flex the shoulder, the lateral fibers abduct the arm, and the posterior fibers extend the shoulder. The rotator cuff muscles are the supraspinatus , infraspinatus , teres minor, and subscapularis . They can be remembered with the mnemonic SITS. The primary function of the rotator cuff muscles is holding the head of the humerus in the glenoid cavity. They act more to assist the other muscles.
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.
The rotator cuff of the shoulder is composed mainly of what?
There are four tendons in the rotator cuff, and these tendons are attached individually to the following muscles: teres minor, subscapularis, infraspinatus, and the supraspinatus.
Which of these muscles is not part of the rotator cuff?
Many muscles are no where near it like my toe, leg, heart, etc.
Name the rotator cuff muscles that are direct or complete synergist?
infraspinatus and teres minor
