teres minor muscle

The teres minor is a small muscle located in the shoulder. It’s part of the rotator cuff group, which helps stabilize and move the shoulder joint. Its main roles are to help rotate the upper arm outward and assist in lifting and rotating the arm. The muscle originates from the outer edge of the shoulder blade (scapula) and attaches to the upper arm bone (humerus). Because of its position and function, the teres minor is important for shoulder stability and smooth arm movements, especially when reaching or lifting objects.
