Includes vocabulary pertinent to joints
Show Answers:

  1. What are the types of joints?
    • Fibrous
    • Cartilaginous
    • Synovial
    • Syndesmosis
  2. Fibrous joints
    Immovable; AKA synarthrosis joints; no joint cavity; example: skull
  3. Cartilaginous joints
    Slightly movable; AKA amphiarthrosis joints; no joint cavity; example: vertebral column
  4. Synovial joints
    Freely moving joints; AKA diarthrosis joints; contains synovial fluid and joint cavity; most common in the body; example: fingers, knee, etc.
  5. Syndesmosis joints
    Unites the bones with a sheet of fibrous tissue, either a ligament or fibrous membrane; only 2 in the body (between the radius & ulna and the tibia & fibula)
  6. Types of synovial joints
    • Plane
    • Ball-and-socket
    • Condyloid
    • Saddle
    • Hinge
    • Pivot
  7. Plane joint
    Permit gliding or sliding movements; example: the acromioclavicular joint (AC joint)
  8. Hinge joint
    Permit flexion and extension only; uniaxial; example: the elbow joint)
  9. Pivot joints
    Allow rotation; uniaxial; a round process of bone fits into a bony ligamentous socket; example: the atlantoaxial joint between the atlas (C1) and the axis (C2)
  10. Saddle joints
    Shaped like a saddle; they are concave and convex where the bones articulate; biaxial; example: the joint between the metacarpal and the trapezium
  11. Condyloid joints
    Permit flexion, extension, abduction, and adduction; biaxial; example: the metacarpophalangeal (knuckle) joints of the fingers
  12. Ball-and-socket joints
    Permit movement in several axes (multiaxial); a rounded head fits into a concavity; example: the hip joint
  13. Hilton's Law
    A nerve that supplies a joint, supplies the muscles that move the joint and the skin that covers the attachments
  14. Degenerative Joint Disease
    Cartilage degeneration (prevalent in the knee); hyaline can't heal because it lacks a blood supply
  15. Osteoarthritis
    Wearing down of bone at a weight-bearing joint (mostly the lower extremities); common in older people and usually affects joint that support their bodies (hips and knees)
  16. Proprioception
    Position and relation of body in space & time; we need to train proprioceptively; joints transmit this sensation which provides information and awareness of movement and position of the parts of the body
