Biomechanics | Anatomy and Functions of the Rotator Cuff

The video tutorial provides an in-depth look at the rotator cuff, a crucial muscle group in human anatomy. It covers the four muscles: supraspinatus, infraspinatus, teres minor, and subscapularis, explaining their roles in shoulder movement. The supraspinatus aids in arm abduction, while the subscapularis is involved in internal rotation. The infraspinatus and teres minor facilitate external rotation. The tutorial highlights the mechanical advantages and potential injuries associated with these muscles, offering a comprehensive understanding of their anatomy and function.

How does the deltoid muscle assist the supraspinatus during shoulder abduction?

What is the significance of the greater and lesser tubercles of the humerus in relation to the rotator cuff muscles?

Why is the supraspinatus muscle considered the most easily injured of the rotator cuff muscles?

What are the roles of the infraspinatus and teres minor muscles?
