hand Flashcards
(4 cards)
hand
the hand consists of the carpals the metacarpals and the phalanges
the wrist or carpus
The carpals form the wrist, also called the carpus.
There are 8 carpal bones, arranged in two irregular rows of 4 bones each:
Proximal row (closer to the forearm)
Distal row (closer to the hand)
These bones are bound tightly by ligaments, which:
Limit movement between individual bones
Stabilize the wrist for strong hand movements
metacarpal or palms
The palm of the hand consists of the metacarpals. The metacarpals are numbered 1 to 5 from the thumb side of the hand toward the little finger. When the fist is clenched, the heads of the metacarpals become obvious as the “knuckles.”
phalanges
The phalanges are the bones of the fingers. Each hand contains 14 phalanges. There are three in each finger (proximal, middle, and distal), except in the thumb, which has only two (proximal and distal).
