Understanding Upper Limb Anatomy Study Guide

A comprehensive guide to the vascular anatomy of the hand, including the palmar arches and digital supply. It also details the principles of arthrokinematics, explaining roll and glide movements, and applies these concepts to specific joints of the wrist, thumb, and fingers (CMC, MCP, IP joints).
