The primary function of the Teres Minor is the modulate the action of the deltoid, preventing the humeral head from sliding upward as the arm is abducted.
12.
These exercises are used to increase stability, strength and range of motion of the Subscapularis, Supraspinatus, Infraspinatus, and Teres minor muscles within the rotator cuff.
13.
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.
14.
The infraspinatus and teres minor rotate the head of the humerus outward ( external, or lateral, rotation ); they also assist in carrying the arm backward.
15.
If the lifter does not lock the elbow, the lateral rotators ( posterior deltoid, infraspinatus, teres minor ) are also involved in preventing internal ( medial ) rotation.
16.
An " I " shape is used for small or linear places, for example an I-shaped piece of tape will be applied to the teres minor or rhomboid minor.
17.
The infraspinatus and teres minor fuse near their musculotendinous junctions, while the supraspinatus and subscapularis tendons join as a sheath that surrounds the biceps tendon at the entrance of the bicipital groove.
18.
External rotation of the shoulder with the arm at a 90-degree angle is an additional exercise done to increase control and range of motion of the Infraspinatus and Teres minor muscles.
19.
This muscle is commonly confused as a rotator cuff muscle, but it is not because it does not attach to the capsule of the shoulder joint, unlike the teres minor muscle for example.
20.
Even though the supraspinatus is the most commonly injured muscle of the four muscles in the rotator cuff, the other three muscles that comprise the rotator cuff are the infraspinatus teres minor, and subscapularis.
