Test 3

  1. What is the degree of movement of a fibrous joint
    All are synarthroses
  2. What is degree of movement of cartilaginous joints
    Synarthroses and ampiarthroses
  3. What is degree of movement of synostoses joints
    All are synarthroses
  4. Degree of movement of synovial joints
    Diarthroses. Exception is gliding joint-ampiarthroses
  5. Describe anatomical classification of fibrous joints
    Bound by collagen fibers, no cavity. Ex(bones of skull, shaft of ulna and radius, and tooth in socket)
  6. Describe anatomical classification of cartligenous joints
    Bound by cartilage, no cavity. Ex. Hyaline, fibrocartilage
  7. Describe the anatomical classification of synostoses joints
    Bound by bone, no cavity. Mandible, frontal bone, sacrum, coccyx
  8. Describe anatomical classification of synovial joints
    • Separated by joint cavity surrounded by articulate capsule lined with synovial membrane secreting synovial fluid.
    • Ex: ball and socket, hinge, pivot, condyloid, saddle, gliding
  9. What is ampiarthroses
    Slightly moveable
  10. What is synarthroses
  11. Describe the bones in synovial joints
    They do not touch and are separated by a space called the joint cavity, filled with synovial fluid to reduce friction.
  12. Identify synovial fluid
    It is secretes by the synovial membrane that lines the articular (fibrous) capsule. Keeps bones separate and surrounds joint cavity.
  13. What is the epiphysis of long bones in the joint cavity covered by and why
    It is covered by articular (hyaline) cartilage. To reduce friction in the joint during movement.
  14. What is the bursa
    A fibrous sac filled with synovial fluid, located between adjacent muscles. Cushions muscles, helps tendons.
  15. What is a tendon sheath
    Elongated cylindrical bursa wrapped around a tendon. Help with fine motor and strength found in hands and feet.
  16. What is a tendon
    Dense regular fibrous connective tissue that attaches muscle to bone. Reinforces joints
  17. What is a ligament
    Dense regular fibrous connective tissue that connects bone to bone. Reinforces joints.
  18. What is diathroses
    Freely moving
  19. What movements do synovial joints allow for?
    Flexion, extension, hyperextension, abduction, adduction, elevation and depression.
  20. Identify ball and socket joints
    Synovial. A hemispherical head and a cup-like depression. Ex shoulder and hip joints
  21. Identify hinge joints
    Synovial. A convex and concave surfaces, more elongated. Ex: (knee and elbow)
  22. Identify pivot joints
    Synovial. Projection fitting into a ring like ligament. Ex(c1/c2)
  23. Identify condyloid joints
    Synovial. One convex surface with similar depression, oval shape. Ex(metacarpophalangeal)
  24. Identify saddle joints
    Synovial. Two surfaces resembling saddle. Ex(opposable thumbs)
  25. Identify gliding joints.
    Synovial. Flat or slightly concave and convex surfaces. Amphiarthroses. Ex (joints between carpal and tarsal bones)
  26. How does aging affect joints
    Aging is the natural process of wear and tear on bones and joints (articular cartilage softens and degenerates)
  27. What are the bones and bone marking that form TMJ
    • Temporal bone: mandibular fossa
    • Mandible: condyloid process
  28. What are the bones and bone markings that form the shoulder
    • Humerus: head
    • Scapula: glenoid cavity
  29. Identify the bones and bone markings that make up the hip
    • Femur: head
    • Os coxa: acetabulum
  30. Identify ligaments of TMJ
    • Sphenomandibular
    • Temporomandinular
  31. Identify ligaments of shoulder
    • Glenohumeral
    • Transverse humeral (holds biceps tendon)
    • Coracohumeral
  32. Identify ligaments of the hip
    • Iliofemoral
    • Ischiofemoral
    • Pubofemoral
  33. What is the stabilizing factor of TMJ
    • Shape of mandibular fossa.
    • Sphenomandibular ligament
    • Temporomandibular ligament
  34. What are the stabilizing factor of the shoulder
    • SITS muscles
    • Bicep brachii tendon
  35. What are the stabilizing factors of the hip
    Twisting effect of ligaments when standing.
  36. What are special characteristics of TMJ joint
    Most often used. Both joints used at same time. Can dislocated spontaneously.
  37. What are special characteristics of the shoulder joint
    Ball and socket. Most moveable joint. Dislocates easy
  38. What are the special characteristics of the hip joint
    Ball and socket. Bears a lot of body weight so is pretty stable.
