Home > Carpal bone

In human anatomy, the carpal bones are the bones of the human wrist.

There are eight of them altogether, and they can be thought of as forming two rows of four.

1 Proximal Row

Scaphoid (or navicular) - this bone, with the lunate, articulates with the radius of the arm.
Lunate - articulates with the radius and the capitate.
Triquetrum - on the ulnar side of the hand, but does not articulate with the ulna.
Pisiform - a sesamoid bone that lies anterior to (closer to the palm than) the triquetrum.

2 Distal Row

Trapezium - the most lateral bone of this row. It articulates with the metacarpal of the thumb.
Trapezoid - articulates with the 2nd metacarpal.
Capitate - articulates with the metacarpal of the middle finger.
Hamate - articulates with the metacarpals of the 4th and 5th fingers. It has a projection called a hook.

Mnemonics that can be useful for remembering the carpal bones are:
