Document Summary

Numbering system usually goes from medial to lateral. In the hand, we start in the numbering of the fingers from the thumb to the pinky (lateral to medial) Thumb: digit #1, index: digit #2, middle finger: #3, wedding finger: #4, pinky: #5. Bones of the digits are called phalanges, individually called phalanx. Phalanx have a head, body and base. Distal phalanx, proximal phalanx, or middle phalanx (not in thumb) Some muscles to proximal phalanx and some to the distal phalanx. 5 metacarpal bones, each extending to one of the digits. End of metacarpals make up your knuckle. Below wrist watch, bottom part of palm. Allow you to make intricate movements of the hand. Organize them: some lovers try positions that they can"t handle (sally left the party to take carmen home) Scaphoid: most lateral proximal carpal bone. in contact with large radial end and most often broken carpal. usually snaps right in the middle.
