Human Arm Anatomy and Function

The video tutorial explains the design and function of a prosthetic arm named Han Solo. It covers the anatomy of the arm, including phalanges, synovial joints, flexor tendons, metacarpals, carpals, forearm bones, and elbow mechanics. The tutorial also describes how these components work together to enable movement, using strings and hydraulics to simulate muscle and tendon functions. The prosthetic arm is designed to mimic natural arm movements, allowing for flexion, extension, and other joint actions.
