  1. What is the weakest part of the skeleton?
    Joints
  2. What is the name of the site where two or more bones meet?
    articulation
  3. What are the 2 functions of joints?
    • *give the skeleton mobility
    • *hold the skeleton together
  4. Which classification of joints focoses on the material binding bones together and whether or not a joint cavity is present?
    Structural Classification
  5. What are the 3 structural classifications?
    • Fibrous
    • Cartilaginous
    • Synovial
  6. What classification is based on the amount of movement allowed by a joint?
    Functional Classification
  7. What are the three functional classes of joints?
    • Synarthroses
    • Amphiarthroses
    • Diarthroses
  8. Synarthroses means
    immovable
  9. Amphiarthroses means
    slightly movable
  10. Diarthroses means
    freely movable
  11. In which structural classification are the bones joined by fibrous tissues?
    Fibrous Structural joints
  12. There is no joint cavity in which structural joint?
    Fibrous structural joints
  13. Most          structural joints are immovable?
    Fibrous Structural joints
  14. What are the 3 types of fibrous structural joints?
    • sutures
    • syndesmoses
    • gomphoses
  15. What type of fibrous structural joint occurs between the bones of the skull?
    Sutures
  16. Which fibrous structural joint is comprised of interlocking junctions completely filled with connective tissue fibers?
    Sutures
  17. What binds bones together, but allows for growth during childhood?
    Sutures
  18. In middle age, skull bones fuse and are called
    synostoses
  19. In what fibrous structural joint are bones connected by fibrous tissue ligaments?
    Syndesmoses
  20. In syndesmoses, movement varies from          to slightly variable.
    immovable
  21. Examples of syndesmoses are the connections between
    tibia and fibula, and radius and ulna
  22. What type of joint has articulating bones that are united by cartilage?
    Cartilaginous
  23. Like Fibrous joints this type of joint also lacks a joint cavity?
    Cartilaginous Joint
  24. What are the 2 types of cartilaginous joints?
    • synchondroses
    • symphyses
  25. In synchondroses, a bar or plate of what kind of cartilage unites the bones?
    Hyaline
  26. All synchondroses are ?
    synarthrotic
  27. Examples of synchondroses are
    • epiphyseal plates of children
    • joint between costal cartilage of the first rib and sternum
  28. Those joints in which thh articulating bones are separated by a fluid-containing joint cavity are
    Synovial joints
  29. Amphiarthrotic joints that are designed for strength and flexibility are
    Symphyses
  30. All of these joints are freely movable diarthroses.
    Synovial Jints
  31. All Synovial joints have
    • Articular cartilage
    • joint cavity
    • articular capsule
    • synovial fluid
    • reinforcing ligaments
  32. Stability in synovial joints is determined by
    • articular surfaces
    • ligaments
  33. Shape determines what movements are possible.
    Articular surfaces
  34. Unite bones and prevent excessive or undesirable motion
    Ligaments
  35. THe 2 muscle attachments across a joint are:
    • Origin
    • Insertion
  36. Attachment to the immovable bone
    Origin
  37. Attachment to the movable bone
    Insertion
  38. An inflammation of a bursa, usually caused by blow or friction
    Bursitis
  39. Inflammation of tendon sheaths typically caused by overuse
    Tendonitis
  40. What type of arthritis is most common, often called wear-and-tear?
    Osteoarthritis
  41. Chronic, inflammatory, autoimmune disease of unknown cause, with an insidious onset.
    Rheumatoid Arthritis.
