Its fibers run obliquely upward and lateralward; the upper ones end in a tendon which is inserted into the lowest of the three impressions on the [[greater tubercle]] of the [[humerus]]; the lowest fibers are inserted directly into the humerus immediately below this impression. ==Relations== The tendon of this muscle passes across, and is united with, the posterior part of the capsule of the [[shoulder-joint]]. ==Action== The Infraspinatus and Teres minor rotate the [[head of the humerus]] outward; they also assist in carrying the arm backward. ==Variations== Sometimes a group of muscle fibres from teres minor may be fused with [[Infraspinatus]]. ==Additional images== <gallery> Image:Shoulderjoint.PNG|Diagram of the human shoulder joint Image:Gray203.png|Left scapula.
