What is rotator cable?
The rotator cable is a semicircular thickening of the glenohumeral joint capsule. It travels between tubercles of the humerus and interweaves with the supra- and infraspinatus muscle tendons. The rotator cable anchors these tendons to the tubercles, playing the role of a suspension bridge.
What are the four rotator cuff muscles?
Parts of the Rotator Cuff
- Supraspinatus controls internal rotation and lifting of the arm.
- Infraspinatus allows you to externally rotate your arm in the shoulder socket.
- Teres minor is a small muscle that helps rotate your arm.
- Subscapularis controls arm abduction (holding your arm out straight, away from your body).
Which of the following muscles is part of the rotator cuff?
Share on Pinterest Four muscles make up the rotator cuff: the subscapularis, teres minor, supraspinatus, and infraspinatus. Together they assist in stabilizing the shoulder joint as well as in performing various arm movements. Four muscles and their attached tendons make up the rotator cuff.
What is the rotator interval?
The rotator interval capsule (RIC) is the anterosuperior aspect of the glenohumeral joint capsule, which merges with CHL and SGHL insertions medial and lateral to the bicipital groove. The CHL arises from the base of coracoid process, traverses through the subcoracoid fat, and inserts on the anterior humerus.
What does intact rotator cuff mean?
For biomechanical testing, the proximal humerus, rotator cuff tendons, and scapula complex were removed. The remaining (intact) cuff muscles were individually detached from the scapula, and the associated muscles were removed.
How many muscles comprise the rotator cuff?
four muscle
Overview. There are four muscle tendons that connect to the shoulder that make up the rotator cuff.
Can you lift arm with torn rotator cuff?
A complete tear makes it impossible to move the arm in a normal range of motion. It is usually impossible to raise the arm away from your side by yourself. Most rotator cuff tears cause a vague pain in the shoulder area. They may also cause a catching sensation when you move your arm.
What are the 4 tendons in the shoulder?
Tendons are the reason a muscle can move the bones in our body when muscles contract. The tendons involved in the shoulder mainly include the long head of the biceps tendon and the tendons of the rotator cuff: supraspinatus, infraspinatus, teres minor and subscapularis.
What tendons are in the rotator cuff?
The rotator cuff tendons are a group of four tendons that connect the deepest layer of muscles to the humerus….Rotator Cuff
- subscapularis.
- supraspinatus.
- infraspinatus.
- teres minor.
