In human life systems, the metacarpal bones or metacarpus, frame the middle of the road part of the skeletal hand situated between the phalanges of the fingers and the carpal bones of the wrist which shapes the association with the lower arm. The metacarpal bones are equal to the metatarsal bones in the foot.The metacarpals shape a transverse curve to which the unbending line of distal carpal bones are settled. The fringe metacarpals (those of the thumb and little finger) shape the sides of the measure of the palmar canal and as they are united they extend this concavity. The file metacarpal is the most solidly settled, while the thumb metacarpal explains with the trapezium and acts freely from the others. The center metacarpals are firmly joined to the carpus by natural interlocking bone components at their bases. The ring metacarpal is to some degree increasingly versatile while the fifth metacarpal is semi-free.
Every metacarpal bone comprises of a body or shaft, and two furthest points: the head at the distal or advanced end (close to the fingers), and the base at the proximal or carpal end (near the wrist).
