Teres minor muscle

The teres minor muscle is one of the four muscles that make up the rotator cuff, the others being: supraspinatus, infraspinatus, and subscapularis.


Gross anatomy

Teres minor originates from the middle third of the lateral border of the scapula, superior to the attachment of the teres major muscle. As it passes superolaterally, it runs adjacent to the lower border of infraspinatus and posterior to the long head of triceps brachii muscle. The lower portion of teres minor runs alongside teres major muscle before the latter passes anterior to the long head of triceps. The tendon of the muscle fuses with the articular capsule of the humerus before inserting on the inferior facet of the greater tubercle.
