Notes
The teres minor muscle is usually not visible because it blends with the πͺ infraspinatus muscle. Both are covered by thick fascia. However, the teres minor may become visible if the arm is held straight out to the side, rotated outward, and pushed downward and backward against resistance.
One of the π rotator cuff muscles.
Relative Positions of Teres Major and Minor Insertions
πͺ Teres major attaches just behind and above on the greater tubercle, while πͺ teres minor grips the front of the 𦴠humerus along the medial edge of the π bicipital groove.
