To understand the anatomy of the hand we first must understand the anatomy of the forearm and wrist. The forearm consists of two bones, the radius and the ulna. Both forearm bones articulate with the carpal bones of the wrist distally. The radius articulates with the cashew shaped scaphoid bone, and the croissant or moon-shaped lunate bone.

There are fourteen phalanges in each hand; each. The hand is located at the distal end of each arm.

Hand Bones - Names & Structure with Labeled Diagrams Hand Bones There are 27 bones in each human hand, with the total number being 54. These bones, along with the muscles and ligaments in the region, give structure to the human hand and allow for all the movement and dexterity of the hands and fingers. These nerves merge to form a network called the brachial plexus before continuing into the arm. Five major nerves extend from the brachial plexus into the arm: the axillary, musculocutaneous, median, radial, and ulnar nerves. Each of these nerves carries information in the form of nerve impulses to and from a particular region of the arm and hand.
