of the wrist and hand. While wrist and hand injuries are not terribly

and Hand Bones
Wrist and hand anatomy begins
with the bones.
The wrist is made up of 8 bones, called the carpals
These bones are arranged in two rows, and are connected with ligaments.
The carpal bones articulate (touch) with each other, and help to allow
for movements of the wrist.
The hand is made up of two different sets of bones. The metacarpals
and the phalanges
. The metacarpals make up the
hand, while the phalanges are your fingers and thumb.
The radius and ulna
are the two
bones that extend from the elbow into the wrist. The radius is on the
thumb side, while the ulna is on the little finger side of the arm.

start just below the elbow and attatch on the carpal bones.
