CARPAL BONES

CARPAL BONES

There are eight carpal bones .

Carpal bones arranged in two rows

1.       PROXIMAL ROW:scaphoid,lunate,triquetral,pisiform

2.       DISTAL ROW: trapezium,trapezoid,capitates,hamate.

These bones are closely fitted together and held in position by ligaments that allow a limited amount of movement between them.

The bones of the proximal row are associated with the metacarpal bones.

Tendons of muscles lying in the forearm cross the wrist and are held close to the bones by strong fibrous brands,called RETINACULA.

METACARPAL BONES(BONES OF THE HAND)

Metacarpal are five bones form the palm of the hand.

They are numbered from the thumb side inwards.

The proximal ends articulate with the carpal bones and the distal ends with the phalanges.

PHALANGES(FINGER BONES)

There are 14 phalanges, three in each finger and two in the thumb.

They articulate with the metacarpal bones and with the metacarpal bones and with each other,by hinge joints.
