    Study Notes

    Sutures and Syndesmoses

    • Sutures are immovable joints found only between the bones of the skull.
    • Composed of fibrous connective tissue continuous with the periosteum.
    • Over time, sutures ossify and fuse, termed as "synostoses," indicating bony fusion.
    • Inferior tibiofibular joints are syndesmoses, allowing some movement due to longer fibers compared to sutures.

    Cartilaginous Joints

    • Articulating bones are united by cartilage and do not have a joint cavity.
    • Cartilaginous joints are not highly movable, and the space is filled with a cartilage pad.
    • Two types:
      • Synchondroses: Joints united by hyaline cartilage.
      • Symphyses: Joints united by fibrocartilage, allowing slight movements.

    Types of Joint Movements

    • Movement types in various joints:
      • Extension, Abduction, Adduction, Circumduction, Rotation, Pronation, Supination.
      • Additional specialized movements include Dorsiflexion, Plantar flexion, Inversion, Eversion, Protraction, Retraction, Elevation, Depression, and Opposition.

    Synovial Joints

    • Classified by shape of articular surfaces with several types allowing unique movements:
      • Plane (Gliding): Flat surfaces allowing sliding; e.g., sternoclavicular joint.
      • Hinge (Ginglymus): Allows flexion and extension; e.g., elbow and knee joints.
      • Pivot (Trochoid): Permits rotation; e.g., atlantoaxial joint.
      • Condyloid (Ellipsoidal): Dual convex and concave surfaces enabling flexion, extension, abduction, and adduction; e.g., wrist and metacarpophalangeal joints.

    Bursa and Tendon Sheaths

    • Bursae are flattened sacs lined with synovial membrane acting like ball bearings, but they are not joints.
    • Tendon sheaths surround tendons subject to friction and are elongated bursae.

    Injuries and Conditions

    • Dislocations occur when bones are out of alignment.
    • Torn cartilage often affects the meniscus, particularly under compression and shear stress.
    • Bursitis: Inflammation or infection of a bursa; can result from trauma or friction.
    • Specific types of bursitis include:
      • Housemaid's knee: Inflammation of prepatellar bursa.
      • Student's elbow: Olecranon bursitis from prolonged elbow pressure.
