scaphoid
lunate
the distal row consists of the ___, ___ bone, ___ bone, and hamate bone.
trapezium
trapezoid
capiptate
articulating with the distal carpal bones are the 5 ___ bones, forming the hand.
metacarpal
The metacarpals are identified by roman numerals; metacarpal I is most lateral, forming the base of the thumb, and articulates with the ___.
trapezium
The proximal __ of each metacarpal articulates with the carpals.
