The capitate bone gets its name from its distinctive, head-like shape.
The Etymology of Capitate Bone
The term "capitate" is derived from Latin. Let's break down the linguistic roots:
- Latin: capitātus
- Meaning: 'having a head'
- Latin root: capit-
- Meaning: 'head'
Therefore, the name directly reflects the bone's capitulum, or "head." This "head" portion is the rounded, proximal end of the bone that articulates with the scaphoid and lunate bones of the wrist.
Capitate Bone's Position and Shape
- Location: The capitate bone is the largest of the carpal bones located in the wrist. It sits in the center of the wrist, forming the keystone of the wrist's arch.
- Shape:
- It is roughly wedge-shaped, with a rounded, head-like proximal end.
- The bone's distal end has a more irregular shape to articulate with the metacarpal bones of the hand.
Summary
| Feature | Description |

In short, the capitate bone is named for its "head," which is the rounded end that connects with other bones of the wrist. Its Latin-derived name, capitātus, is a clear indication of this distinct feature.
