Joints (Classification base on structure: (Synovial joints: freely movable…

- - - - sutures
        
        found in the skull
        
        thin layer of dense fibrous connective tissue uniting the bones of the skull
        
        irregular/interlocking edges give added strength and prevent fracture
      - syndesmoses
        
        greater distance between articulating bones w/ more fibrous connective tissue than sutures
      - gomphoses
        
        ligament holds cone shaped peg in bony socket
- - - - bone surfaces are flat or slightly curved
      - side to side movement only
      - rotation prevented by ligaments
      - ex: intercarpal joints, vertebrocostal joints
    - - convex surface of one bone fits into concave surface of 2nd bone
      - uniaxial like a door hinge
      - movements produced: flexion, extension, hyperextension
      - ex: knee, elbow, ankle
    - - round surface of bone articulates w/ ring formed by 2nd bone and ligaments
      - rotation around longitudinal axis
      - ex: atlantro-axial joint
    - - multiaxial: flexion/extension, adbuction/adduction, rotation
      - ex: shoulder joint, hip joint
- - - - connecting material is hyaline cartilage
      - immovable
      - located in the epiphyseal plates of long bones and connects the ribs to the sternum
    - - ends of articulating bones covered w/ hyaline cartilage
      - thin disc of fibrocartilage connects bone
      - slightly movable
      - located in inverterbal disc
