About this quiz
The wrist, or carpus, is built from eight small bones. Beyond them, each hand has five metacarpals in the palm and fourteen phalanges in the fingers and thumb.
- The lunate is named for its moon shape and the pisiform for its pea shape.
- The pisiform sits inside the tendon of a forearm muscle.
- The hamate has a hook: a prominent process that projects towards the palm.
- Across both wrists there are 16 carpal bones.
