Skeletal Diagram Of Hand A total of 27 bones constitute the basic skeleton of the wrist and hand. the hand is innervated by 3 nerves — the median, ulnar, and radial nerves — each of which has sensory and motor components. the muscles of the hand are divided into intrinsic and extrinsic groups. the anatomy of the hand is complex, intricate, and fascinating. The bones of the hand provide support and movement to the soft tissues. they can be categorised into three different types: carpal bones (proximal) – a set of eight irregularly shaped bones. they are located in the area of the wrist. metacarpals – a set of five bones, each one related to a digit. they are located in the area of the palm.
