The Thumb Extensors

This lesson covers the Extensors (and Abductor) of the thumb, the Abductor Pollicis Longus, Extensor Pollicis Brevis, and Extensor Pollicis Longus. The video covers the origin, insertion, function, and surface landmarks of the muscle, and also clearly explains supination and pronation, describing how the lower arm moves. This makes a complex topic understandable, easy to follow, and will help you draw the figure better!
