Shoulder Elbow Paper Puzzles Tutorial

The video tutorial guides students through an activity involving the identification and sorting of various nerves and muscles using pictures. It covers the dorsal scapular, long thoracic, suprascapular, and musculocutaneous nerves, as well as muscles like the supraspinatus, trapezius, and biceps. The tutorial also explores muscle actions such as protraction, rotation, and abduction, and reviews the innervations of these muscles.
