![]() Long bone: Helps to facilitate movement and support the weight of the body. There are five types of bones in the human skeletal system: long, short, flat, irregular, and sesamoid. They can be grouped together by function and structure, such as ball-and-socket, hinge, and pivot joints. ![]() Joint: Joints hold the bones of the skeleton together and support movement. Tendon: A tough, flexible and inelastic band of fibrous connective tissue that connects muscles to bones. Ligament: A small band of dense, white, fibrous elastic tissue that connects the ends of bones together form a joint or assists in holding organs in place. The skeletal system is composed of four main types of connective tissue:īone: A rigid form of connective tissue that is part of the skeletal system of vertebrates and is composed principally of calcium. It consists of 126 bones that include both the upper and lower limbs, feet, ankles, shoulders, and pelvis. The appendicular skeleton supports the appendages. It also provides protection and support for the brain, spinal cord, and vital organs and a surface for muscles to attach. The axial skeleton forms the central axis of the human body and is composed of 80 bones that include the bones of the skull, the ossicles of the middle ear, the hyoid bone of the throat, the vertebral column, and the thoracic cage. The human skeletal system is divided into two main parts: Storage of minerals, particularly calcium.The main functions of the skeletal system are: It also consists of the joints, cartilage, tendons, and ligaments that connect them. Did you know that the adult human skeletal system contains 206 bones? The human skeleton provides the body with a multifunctional structure.
