The hand is part of the upper limb below the forearm and wrist. In the supinated anatomical position, the palm is facing anteriorly and the dorsum posteriorly.

The bones of the hand are:

carpals (8)
- scaphoid
- lunate
- triquetrum
- pisiform
- trapezium
- trapezoid
- capitate
- hamate
metacarpals (5)
phalanges (13)
- thumb
  - proximal and distal phalanges
- 2nd to 5th fingers
  - proximal, middle and distal phalanges

The wrist joint is superior. Hand movement is complex and occurs across many joints, including those involved in wrist flexion.

Muscles of the hand can be divided into:

extrinsic muscles whose tendons arise from muscle bellies within the forearm, and
intrinsic muscles (mnemonic) whose muscle bellies are located within the hand
