Researchers Unveil Role of Teres Major Muscle in Upper Arm Movement
Researchers have recently explored the function and location of the teres major muscle, a key player in upper arm movement and stability.
The teres major muscle, situated on the underside of the upper arm, plays a crucial role in humeral movement and stability. It begins just below the armpit and ends at the top of the humerus, working alongside the latissimus dorsi to move the humerus back and down when extended. This medial rotator also aids in controlling humeral movements and stabilising the head of the humerus.
Blood supply to this muscle is provided by arteries, while nerves from the lower subscapular nerve offer sensation. The teres major muscle, flat in shape, is part of the scapulohumeral muscle group, located near the teres minor, another rotator cuff muscle.
The teres major muscle, recently studied by researchers, is vital for upper arm movement and stability. Its function and location have been further clarified, contributing to our understanding of human anatomy and potential treatments for related injuries.
