Carpal bone

From Free net encyclopedia

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.

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.

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:

• "Some Lovers Try Positions That They Cannot Handle"
• "Students Like The Professor To Teach Complex Hypotheses"
• "She Likes Taking Prostitutes To The Calley Hotel"
• "She Looks Too Pretty Try To Catch Her"

A Hindi version which is quite funny and hence popular among students in India, is:

• "Sneh Lata Tinde Paka Tere Tinde Catchey Hain"

which can be roughly translated as an exhortation to a woman called Sneh Lata, asking her to properly cook a vegetable!
