There are 27 bones in each hand, divided into 8 Carpal bones (wrist), 5 Metacarpal bones (palm), and 14 Phalanges (fingers).
The Carpal bones are arranged in two rows of four. The row nearest the forearm is called the Proximal Row. The row nearest the palm is called the Distal Row. The carpal bones are small, cube-shaped, and each has six sides (except for the Pisiform, which has five sides).
The Metacarpal bones are the five long bones of the palm. They are named the first, second, third, fourth and fifth Metacarpal, the first being the one leading to the thumb.
The Phalanges are the bones of the fingers. Each finger contains three, while the thumb has two.
