11.8- The Rotator Cuff 2 Quiz Please sign up for the course before taking this quiz. Chronic tears to the rotator cuff usually occur where?1 In the fascia of the muscles of the rotator cuff In the belly of the infraspinatus At or near the muscle's tendon In the belly of the supraspinatus Dislocation of the glenohumeral joint during movement is prevented, in part, by the biceps tendon.1 True False Dislocation of the glenohumeral joint during movement is prevented, in part, by the supraspinatus.1 True False Dislocation of the glenohumeral joint during movement is prevented, in part, by the rotator cuff.1 True False The rotator cuff muscles insert on the scapulae posteriorly and the clavicle anteriorly.1 True False The rotator cuff muscles originate on the anterior and posterior scapulae and insert on the humeral head.1 True False Choose the selection that correctly lists these three muscles from the most superior to the most inferior.1 Supraspinatus, Infraspinatus, Teres Minor Teres Minor, Supraspinatus, Infraspinatus Infraspinatus, Teres Minor, Supraspinatus Infraspinatus, Supraspinatus, Teres Minor Supraspinatus, Teres Minor, Infraspinatus Because the infraspinatus originates on the medial border of the scapulae and inserts on the posterior head of the humerus, when it is behaving as an agonist, it initiates which movement at which joint?1 It initiates lateral rotation at the glenohumeral joint. It initiates lateral rotation at the scapulothoracic joint. It initiates medial rotation at the scapulothoracic joint. It initiates medial rotation at the glenohumeral joint. It initiates abduction at the scapulothoracic joint. Because the supraspinatus originates on the medial border of the scapulae and inserts on the most superior part of the head of the humerus, if it were behaving as an agonist, it initiates which movement at which joint?1 It initiates lateral rotation at the scapulothoracic joint. It initiates abduction at the glenohumeral joint. It initiates medial rotation at the scapulothoracic joint. It initiates medial rotation at the glenohumeral joint. It initiates lateral rotation at the glenohumeral joint.
