Movement

Movement in arthropods is achieved by muscles attached inside the skeleton, which coordinates with their nervous system. The muscles work by generating force through contradicting, then transferring that force to their exoskeleton. At each body joint, muscles are either positioned to flex the joint or extend it. The pull of muscles against the exoskeleton allows the arthropod to function accordingly, whether it is by beating their wings, flexing their legs, or thumping their flippers.
