Hand and Wrist

The hand and wrist are made up of many different bones, muscles and ligaments that enable a wide range of movements. The wrist links hand to the arm. The wrist is a complex mechanical system made of 8 bones known as the carpal bones.  The hand has 19 bones: 5 elongated metacarpel bones, which are next to the wrist and make up the palm; 14 phalanges which make up the fingers. These 19 bones collectively form 14 separate joints. The knuckle joints,metacarpophalangeal (MCP) joints, join the fingers to the palm. The interphalangeal (IP) joints are the finger joints. There are synovial joints between the metacarpals and phalanges—these bones are also covered with articular cartilage.
