label the ligament, shell, muscle attachment, exoskeleton, hinge , joint

Basically you just have to name any two random parts just the way you feel. The middle section can be a hinge/joint/point of attatchement, etc........ the whole structure is exoskeletal.......... and you know- the full thing is a shell, so label it anywhere
