The skeletal system of human is composed of four main connective tissues i.e. bones, ligaments, tendons, and joints.
Bone is composed of collagen and calcium phosphate. Collagen is a protein that provides a soft framework to the skeleton, whereas calcium phosphate is a mineral that provides strength to the framework. Ligaments are the bands of tough elastic tissue that are present around your joints.
These ligaments connect one bone to another bone. A tendon is a type of fibrous connective tissue which attaches the muscle to bone. The area or region where two or more bones meet with each other is called joint so we can say that skeletal system is composed of bones, ligaments, tendons, and joints.
