How is a arthropods skeleton different from a human skeleton?

Arthropods have an exoskeleton made of chitin, which provides structural support and protection while allowing for mobility through jointed appendages. In contrast, humans possess an endoskeleton made of bone, which is internal and supports the body while allowing for growth and healing. The exoskeleton of arthropods must be periodically molted to accommodate growth, whereas the human skeleton grows continuously with the body. Additionally, arthropods rely on muscles attached to the exoskeleton for movement, while humans have muscles attached to bones.
