Document Summary
Types of joints: a synarthrosis joint is an immovable joint. Suture: located in the bones of the skull. Gomphoisis: connection between a tooth and its socket. Synostosis: are totally immovable joints: an amphiarthrosis joint is a slightly movable joint. Syndesmosis: a ligament band connecting bones (tibia and fibula or ulna and radius) Symphysis: bones are separated by a wedge of a pad of fibrocartilage (pubis ad intervertebral discs: a diarthrosis joint is a freely movable joint. The components that make up a synovial joint are: fibrous articular capsule, synovial cavity, synovial membrane, haversian fat pad, articular (hyaline) cartilage, ligaments, tendons, bursae. The synovial membrane contains phagotic cells and b cells which make. Joint classification: on a basis of their shapes and articulating surfaces, synovial joints can be classified as gliding, hinge, pivot, ellipsoidal, saddle, or ball-and-socket, range of motion. Levers: a lever is a rigid structure, such as a bone, that moves at a fixed point called a fulcrum.
