The anatomy of the hand consists of bones, muscles, tendons, and nerves that work together to enable movement and function. The hand has 27 bones, including the carpals in the wrist, the metacarpals in the palm, and the phalanges in the fingers. These bones provide structure and support, allowing for a wide range of motion. Muscles in the hand can be categorized into intrinsic and extrinsic groups. The intrinsic muscles, located within the hand, control fine movements, while the extrinsic muscles, originating in the forearm, facilitate stronger actions. Nerves, such as the median, ulnar, and radial nerves, provide sensation and motor control, making the hand highly functional.
