The arrangement of the metacarpal bones is typically structured to provide both stability and flexibility to the hand, with five elongated bones that correspond to each finger. They are arranged in a slightly curved line, allowing for an optimal grip and dexterity. This conclusion is based on the anatomical design of the hand, where the metacarpals serve as the framework that supports the fingers while allowing a wide range of motion. Additionally, their positioning is influenced by the need for balance and coordination during various hand movements.
