Bones and Joints of the Hand

This video from Catalyst University covers the anatomy of the hand bones, dividing them into carpals, metacarpals, and phalanges. It explains the arrangement of carpal bones into proximal and distal rows, introduces a mnemonic for memorizing them, and discusses the metacarpals and phalanges. The video also details the various joints in the hand, including intercarpal, carpometacarpal, and metacarpophalangeal joints, and their types, such as synovial, saddle, and hinge joints.
