Joints Joints are the connection sites between two or more bones. When a muscle pulls on a bone, the bone moves only at the joint. The study of joints is known as arthrology ; kinesiology is the study of musculoskeletal movement. Joints can be classified by their freedom of movement or by the way the bones are joined together . A diarthrosis is a freely movable joint; an amphiarthrosis is slightly movable; a synarthrosis results in little or no movement at the joint. For our purposes, we will discuss each joint based upon its anatomy. Anatomically, the types of joints are fibrous joints, cartilaginous joints, bony joints and synovial joints. Fibrous Joints Fibrous joints have collagen fibers spanning the space between the bones. These joints include sutures, gomphoses and syndesmoses. Sutures are the immovable fibrous joints that bind the bones of the skull to each other. Serrate

Unformatted text preview: sutures look like interlocking wavy lines and occur in the coronal, sagittal and lambdoid sutures. Squamous sutures have overlapping edges and occur between the temporal and parietal bones. Plane sutures have straight, non-overlapping edges and occur between the palatine processes of the maxillae. Gomphoses are the joints that holds teeth in their sockets. The tooth is held in place by fibrous periodontal ligaments . These joints allow the tooth to move a little while chewing. The third type of fibrous joint are syndesmoses . These are joints in which two bones are bound together by an interosseus membrane . This is the most movable of the fibrous joints and can be found between the radius and ulna and between the tibia and fibula....
