Subscapularis muscle

This video tutorial by Matt from Kenhub covers the subscapularis muscle, a key component of the rotator cuff. It discusses the muscle's origin, insertion, innervation, and function. The subscapularis originates from the subscapular fossa and inserts on the humerus. It is innervated by the subscapular nerve, which is part of the brachial plexus. The rotator cuff stabilizes the shoulder joint, and the subscapularis aids in internal rotation of the humerus. The video encourages interactive learning through Kenhub's resources.

Describe the main function of the rotator cuff.
