Understanding Wrist Bones
Smallest Bone in the Wrist: Uncovering Its Identity The human wrist has many small bones called wrist bones. These bones help us move our wrist and keep it flexible. They are part of the wrist bone structure.
Anatomical Structure of the Wrist Bones
The wrist bones are made up of eight small bones. They form two rows: the proximal and distal rows. The proximal row has the scaphoid, lunate, triquetrum, and pisiform bones. The distal row has the trapezium, trapezoid, capitate, and hamate bones.
Each bone has a special shape and function. They work together for the wrist’s complex movements.
Classification of Carpal Bones
The wrist bones are sorted by where they are and what they do. The proximal row bones, like the scaphoid and lunate, are near the forearm. They help with wrist motion.
The distal row bones, like the trapezium and capitate, are closer to the metacarpals. They help with hand functions.
Here is a detailed table summarizing the names, positions, and general functions of these carpal bones:
| Carpal Bone | Position | Function |
|---|---|---|
| Scaphoid | Proximal Row | Stabilizes the wrist, facilitates radial deviation |
| Lunate | Proximal Row | Facilitates wrist flexion and extension |
| Triquetrum | Proximal Row | Supports wrist motion and ulnar deviation |
| Pisiform | Proximal Row | Serves as a sesamoid bone, enhancing leverage for tendons |
| Trapezium | Distal Row | Allows thumb opposition and fine motor skills |
