Scaphoid

AKA Navicular bone, boat-shaped and lies on the radial side of the wrist

Lunate

Crescent half moon shaped, semilunar bone that lies between the scaphoid and triquetral bones.

Triquetral

Triangular shaped bone that lies on the ulnar side of the wrist.

Pisiform

Lies anterior to the triquetral bone, not medial to it. Forms a prominence on the anterior medial part of the wrist and is readily palpable.

Trapezium

Lies on the radial side of the wrist in the distal row of carpal bones

Trapezoid

Lies between the trapezium and capitate bone

Capitate

Lies between the trapezoid and hamate bones

Capitate

“Largest carpal bone”

Hamate

Lies on the Ulnar border of the wrist

Hamate

Has a hook-like process called the hamulus

First Metacarpal Bone

Thumb side of metacarpal

Fifth Metacarpal Bone
