• True

• False

The most commonly fractured carpal bone located on the radial side of the hand, distal to the styloid process of the radius, is the (a)   .

• Scaphoid
• Lunate
• Triquetrum
• Pisiform

Located distal to the scaphoid, the small bone that articulates with the base of the first metacarpal and is the source of the thumb’s unique movements is called the (a)   .

• Trapezium
• Capitate
• Hamate
• Triquetrum

Match the following carpal bone names with their translations:

• pisiform

• hooked

• hamate

• boat-shaped

• lunate

• pea-shaped

• scaphoid

• head-shaped

• capitate

• crescent-shaped

Which bone is located most laterally in the proximal row of the wrist?

• Scaphoid

• Lunate

• Triquetrum

• Pisiform

Refer to the diagram of the carpal bones. Match the following carpal bones to their correct position:

• Hamate

• Lateral bone in the distal row

• Pisiform

• Small bone on the anterior surface of the triquetrum

• Trapezium

• Most central carpal bone

• Capitate

• Medial bone in the distal row

Which carpal bone is located most medially in the proximal row of the wrist?

• Scaphoid

• Lunate

• Triquetrum

• Pisiform

(a)   is a bone that is part of the distal row of carpal bones.

• Scaphoid
• Trapezium
• Lunate
• Pisiform

Fill in the blank: The scaphoid, lunate, triquetrum, and pisiform form the ________ row of carpal bones.

The pisiform and the hook of the hamate form a small channel called the (a)   , through which the ulnar nerve and artery pass.

• Tunnel of Guyon
• Carpal tunnel
• Cubital tunnel
• Tunnel of Hamate
