hand

Terminal part of the forearm with a tactile and prehensile function and a thumb opposable to the other fingers. The skeleton of the hand has 27 bones.

distal phalange

Last phalange of the finger bearing a nail.

proximal phalange

First phalange of the finger; it is connected to the metacarpus.

distal phalange

Last phalange of the finger bearing a nail.

middle phalange

Second phalange of the finger between the proximal and distal phalanges. The thumb does not have a middle phalange.

proximal phalange

First phalange of the finger; it is connected to the metacarpus.

metacarpal

Each of the five bones forming the metacarpus. The metacarpal bone of the thumb is very mobile.

hamate

Bone of the anterior row of the carpus, articulating especially with the metacarpal bones of the third and little fingers.

triquetral

Last bone in the posterior row of the carpus, set opposite the thumb.

pisiform

Bone of the posterior row of the carpus; it is the smallest of the carpal bones.

lunate

Bone of the posterior row of the carpus articulating especially with the radius to form the wrist.

trapezium

Bone of the anterior row of the carpus articulating especially with the metacarpal bone of the thumb.

trapezoid

Bone of the anterior row of the carpus articulating especially with the metacarpal bone of the index finger.

capitate

Bone of the anterior row of the carpus articulating especially with the metacarpal bone of the middle finger.

scaphoid

The largest bone in the posterior row of the carpus articulating with the radius to form the wrist.

radius

Long bone making up the outer section of the forearm; it is connected especially to the carpal bones to form the wrist joint.

ulna

Long bone forming the inner portion of the forearm, and articulating especially with the radius.

carpus

All eight short articulated bones, laid out in two rows, forming the wrist and giving it a wide range of motion; it connects the radius to the metacarpus.

metacarpus

All five long bones forming the palm of the hand; they link the anterior row of the carpus to the proximal phalanges.

phalanges

Articulated bones forming the skeleton of the fingers; each finger has three, while the thumb has two.
