Muscles of the foot

This tutorial by Matt from Kenhub focuses on the infraspinatus muscle, part of the rotator cuff in the upper extremity. It covers the origin, insertion, anatomy, and function of the infraspinatus, highlighting its role as a strong external rotator and its assistance in abduction and adduction. The rotator cuff's primary function is to stabilize the humeral head in the glenoid cavity and facilitate shoulder movements. The video concludes with a call to explore more anatomy resources on Kenhub.
