  1. what is a joint?
    place of contact between bones, bone and cartilage, or bones and teeth.
  2. Structural Classification: Fibrous Joint
    • has no joint cavity
    • bones held together by dense connective tissue
  3. Structural Classification: Cartilaginous Joint
    • has no joint cavity
    • joined by cartilage
  4. Structural Classification: Synovial joint
    • fluid- filled joint cavity seperating surfaces of bones
    • surface enclosed within connective tissue
    • bones attached by ligaments
  5. Functional classification: Synarthrosis
    immobile joint (fibrous or cartilaginous)
  6. Functional classification: Amphiarthrosis
    • slightly mobile joint
    • (fibrous or cartilaginous)
  7. Functional classification: Diarthrosis
    • freely mobile joint
    • all synovial joint
  8. what determines mobility and stability of each joint?
    structure of each joint
  9. Fibrous joints are connected by ____ ____ ____ _____
    dense regular connective tissue
  10. fibrous joints have no ____ _____
    joint cavity
  11. Fibrous joints can be either ____ or only _____ _____
    immobile or slightly mobile
  12. what are the 3 most common types of fibrous joints?
    • gomphoses
    • sutures 
    • syndesmoses
  13. what is gomphoses?
    peg in a socket= teeth
  14. what are sutures?
    • immobile fibrous joints 
    • found in the skull
    • irregular edges
    • ossified in older adult
  15. what are syndesmoses?
    • joined by long strand of dense connective tissue
    • amphiarthroses 
    • between radius, ulna, tibia, and fibula
    • provides a pivot 
    • bound by interosseous membrane
  16. cartilaginous joints lack a ______ ______
    joint cavity
  17. cartilaginous joints can be _____ or _______
    • immobile or slightly mobile
    • synchondroses or symphyses
  18. what is synchondrosis?
    • bones joined by hyaline cartilage
    • all immobile (synarthroses)
  19. what is symphysis?
    • pad of fibrocartilage between articulating bones
    • amphiarthroses
  20. what is the largest and most complex diarthrosis?
    knee joint
  21. knee joint is primarly a ____ joint
  22. what are the two seperate articulations of the knee joint?
    • tibiofemoral joint
    • patellofemoral joint
  23. where can you find tibiofemoral joints?
    between condyles of femur and condyles of tibia
  24. where can you find patellofemoral joints?
    between patella and patellar surface of femur
  25. what muscle tendon passes over knee's anterior surface?
    quadceps femoris muscle tendon
  26. the patellar ligament extends from _____ to _________
    • patella 
    • tibial tuberosity
  27. in the knee joint, what reinforces lateral surface of joint? This also extends from ____ to _____. Prevents _______ of leg at the knee.
    • fibular collateral ligament
    • femur
    • fibula
    • hyperadduction
  28. what reinforces the medial surface of knee joint? Extends from _____ to ______ and prevents ________ of leg at the knee?
    • tibial collateral ligament 
    • femur
    • tibia
    • hyperabduction
  29. what partially stabilize joint medially and laterally?
    medial meniscus and lateral meniscus

  34. what prevents hyper flexion?
    PCL (posterior Cruciate Ligament)
  35. when do joints start to develop?
    by 6th week of development
