which muscles are part of the rotator cuff
Rotator cuff In anatomy, the rotator cuff [1]) is a group of muscles and their tendons that act to stabilize the shoulder. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are the supraspinatus muscle, the infraspinatus muscle, teres minor muscle, and the subscapularis muscle.
Cerebellar tentorium It covers the top of the cerebellum, and supports the occipital lobes of the brain.
Small intestine Food from the stomach is allowed into the duodenum through the pylorus by a muscle called the pyloric sphincter.
Rotator cuff The rotator cuff muscles are important in shoulder movements and in maintaining glenohumeral joint (shoulder joint) stability.[4] These muscles arise from the scapula and connect to the head of the humerus, forming a cuff at the shoulder joint. They hold the head of the humerus in the small and shallow glenoid fossa of the scapula. The glenohumeral joint has been analogously described as a golf ball (head of the humerus) sitting on a golf tee (glenoid fossa).[5]
Capitulum of the humerus It articulates with the cupshaped depression on the head of the radius, and is limited to the front and lower part of the bone.
Triceps brachii muscle With its origin on the scapula, the long head also acts on the shoulder joint and is also involved in retroversion and adduction of the arm.[1]
