The teres minor (Latin teres meaning 'rounded') is a narrow, elongated muscle of the rotator cuff. The muscle originates from the lateral border and adjacent posterior surface of the corresponding right or left scapula and inserts at both the greater tubercle of the humerus and the posterior surface of the joint capsule.
Empty beer can test: a positive test indicates rotator cuff tear, specifically, supraspinatus muscle tear; Drop arm test: a positive test indicates a supraspinatus tear; External Rotation test: a positive test indicates an infraspinatus or teres minor tear; Lift-off test: a positive test indicates subscapularis pathology
Teres minor), 15. Biceps muscle. The rotator cuff (SITS muscles) is a group of muscles and their tendons that act to stabilize the human shoulder and allow for its extensive range of motion. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are: supraspinatus muscle; infraspinatus muscle; teres minor muscle
With this test, the strength of external rotators of the shoulders are examined, including the infraspinatus and teres minor muscles. [30] Patients are instructed to keep their forearms bent at right angles while holding their arms at their sides. Resistance will be applied on patients while the patient rotates their shoulders.
The impinged structures include the supraspinatus muscle, teres minor muscle, and the infraspinatus muscle. The Hawkins–Kennedy test is considered to be a highly sensitive test (79%) [3] and thus a positive Hawkins–Kennedy test suggests that injury is likely.
The teres major attaches to the outer part of the back of the scapula, beneath the teres minor, and attaches to the upper part of the humerus. It helps with medial rotation of the humerus. [3] Muscles from the front. Muscles from the chest wall that contribute to the shoulder are: [3]
infraspinatus, teres minor, pectoralis major, latissimus dorsi: 2 1 infraspinatus: Upper limb, Shoulder, rotator cuff, Right/left infraspinous fossa of scapula: middle facet of greater tubercle of humerus: suprascapular artery, circumflex scapular artery: suprascapular nerve: laterally rotates, adducts, and stabilises humerus
The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, infraspinatus, teres minor and supraspinatus. [9] These muscles attach to the surface of the scapula and are responsible for the internal and external rotation of the glenohumeral joint, along with humeral abduction.
