Please revise the part of the video where you talk about the Upper and Lower Subscapularis nerves. You state that the subscapularis muscle and teres majors are abductors but in many textbooks, the subscapularis rotates the head of the humerus medially (internal rotation) and ADDUCTS it; when the arm is raised, it draws the humerus forward and downward. The teres major is a medial rotator and ADDUCTOR of the humerus and assists the latissimus dorsi in drawing the previously raised humerus downwards and backward (extension, but not hyperextension).
Radial nerve doesn't entirely provide sensation to the opposite side of the supply of median nerve. Median nerve does supply sensation to the dorsal side of the 2nd and 3rd fingers
