The skeletal system serves important functions in the body. It provides the general shape and form of the human body. Without it, we will be amoeba-like and gelatinous in form. It also holds several tissues of the body together, serves as protection for organs, and is responsible for the movements that the body performs. It is an integral part of the human structure because they provide the necessary attachments that the muscle fibers need in order to perform different motions.
