Which structures of the body have more bones for their size than any other part of the body?

The wrist and the hand have more bones in them for their size than any other part of the body. There are 8 carpals in the wrist between the forearm and the palm of the hand; 5 metacarpal bones that form the palm of the hand between the wrist, thumb, and fingers; and 14 phalanges or finger bones. The presence of many small bones in the wrist and hand with the many movable joints between them makes the human hand highly maneuverable and mobile.
