Hand and Wrist

Hand and Wrist

The hand and wrist are made up of many bones, muscles, tendons, and ligaments that enable a wide range of movements. The hand has two rows of four bones each called the carpals. Long, thin bones radiate out from one row of carpals to form the fingers and thumb. The radius and ulna bones of the forearm form a joint with the first row of carpals. The radius is the larger bone on the thumb side and the ulna is the smaller bone on the pinky side. The ends of the bones are covered with cartilage that enables the bones to move smoothly.

Long tendons extend from the muscles in the forearm through the wrist and attach to the fingers and thumb bones. Tendons are bands of connective tissue that attach the muscles to the bone, enabling the muscles to move the bones. Ligaments are tough bands of connective tissue that connect the bones for support and stability.
