From ArticleWorld
The musculoskeletal system is the part of an animal’s body that provides the animal’s structure and shape, and allows for movement of the animal’s body. There are three types of skeletal structures. Vertebrates have an endoskeleton that is inside the body. Arthropods have an exoskeleton that provides bodily structure by being located outside of the body. Hydrostatic musculoskeletal systems use water pressure inside multiple pouches, which gives animals, like annelids, or worms, a variable structure. Muscles of varying types contract and allow for mobility of the animal.
