Anatomy of the Hand

The human hand is a marvel of biological engineering, consisting of 27 bones, 34 muscles, and numerous ligaments and tendons that work together to perform intricate movements. The fingers, in particular, are composed of phalanges, which are the small bones that form the digits. Each finger, except the thumb, consists of three phalanges: the proximal, middle, and distal. The thumb has only two phalanges.

The fingers are connected to the hand via metacarpal bones, which are located in the palm. The joints between these bones allow for the flexibility and range of motion needed for various tasks. The coordination between muscles and tendons is crucial for finger movement, with each finger having its own set of tendons that attach to muscles in the forearm. This intricate system enables the precise control necessary for activities ranging from typing to playing musical instruments.
