Document Summary
Two bones may be in direct contact or separated by: cartilage, fluid, fibrous tissue. Sutural ligament composed of connective tissue: gomphosis (joint between teeth and jaw)(think of gum) Fibrous: synchondrosis (joint within epiphysis of bone) Binds diaphysis and epiphysis: synostosis (joint between two fused bones)(i. e. coxal bones) No boundary between fusion, totally rigid: amphiarthroses (slightly movable joints) Syndesmosis (ligaments connecting two bones with limited motion. Between radius and ulna, tibia and fibula. Symphysis (bones separated by wedge or pad of cartilage) Between pubic bones of two coxal bones + intervertebral discs fibrous. Found at end of long bones: ex, shoulder, elbow, hip, knee joints. Three main functions: provide lubrication, nourish chondrocytes, shock absorption. Six basic characteristics: a joint capsule, presence of articular cartilages. 3. which acts as: lubricate, nourish, shock absorber, synovial membrane, accessory structures, sensory nerves and blood vessels. Plane joints (gilding joints: monoaxial movement in only one plane. Pivot joints: rotational movements including supination and pronation (monoaxial)
