Infraspinatus muscle

This video tutorial covers the anatomy of the teres minor muscle, part of the rotator cuff in the upper arm. It explains the muscle's origin from the lateral scapula border and insertion on the greater tubercle of the humerus. The axillary nerve innervates the teres minor, which plays a role in external rotation and stabilization of the shoulder joint. The tutorial also compares the teres minor with the teres major, highlighting their different functions. Additional resources for further learning are provided.
