Origins

  • Upper two thirds of the lateral (axillary) border of the 🦴 scapula

Insertions

Actions

  • External (lateral) rotation of the humerus
  • Weak adduction of the humerus
  • Assists in stabilizing the ⚙️ glenohumeral joint as part of the rotator cuff

The teres minor muscle is usually not visible because it blends with the 💪 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 📓 rotator cuff muscles.

Relative Positions of Teres Major and Minor Insertions

Teres major attaches just behind and above on the greater tubercle, while 💪 teres minor grips the front of the 🦴 humerus along the medial edge of the 📍 bicipital groove.
