5 Written questions

5 Matching questions

  1. parts of long bone (7)
  2. callus
  3. osteon
  4. osteoblast
  5. osteocyte
  1. a 1. Diaphysis - shaft
    2. Epiphysis - bulby ends, where muscles attach
    3. Epiphyseal plate or disk - cartilage, plate=still growing, line=stopped growing (white line)
    4. Medullary or marrow cavity - hollow, living bone has marrow
    5. Periosteum - around the bone
    6. Endosteum - lines the cavity, inside
    7. Articular cartilage - covers head & bottom
  2. b specialized repair tissue that binds the broken ends of the fracture together.
  3. c bone cell (mature bone cells)

    Maintains matrix
  4. d cylinder shaped structural unit in compact bone
  5. e bone forming cell
    Builds matrix

5 Multiple choice questions

  1. 1. Most bones develop this process
    2. Formation of primary ossification center and marrow cavity in shaft of model
    a. Bony collar developed by osteoblasts
    b. Chondrocytes swell and die
    c. Stem cells give rise to osteoblasts and clasts
    d. Bone laid down and marrow cavity created

    epiphysis - needs to be remodeled (reshaped)
    bone grows on the outside and then an inner layer disappears by osteoclasts. this is so the bones don't get too heavy
  2. around
  3. bone absorbing cell

    breaks down the matrix
  4. curvature of the spine
  5. 1. Myeloid (myelo=bone marrow) tissue
    2. In medullary cavity (long bone) and among trabeculae (spongy bone)
    3. Site for the production of blood cells
    a. Red marrow
    i. In vertebrae, ribs, sternum, pelvic girdle and proximal heads of femur and humerus in ADULTS
    b. Yellow marrow
    i. Fatty marrow of long bones in adults

    Note: kids have RBC in marrow in long bones b/c still growing

5 True/False questions

  1. lacunaedimples, osteocyte sits in lacunae

          

  2. osteoblasts & osteoclast & calcium1. during bone formation osteoblasts remove calcium from blood, lowering its circulating levels
    2. when osteoclasts are active and breakdown of bone predominates, calcium is released into blood & circulating levels will increase.

          

  3. repair of fractures 2/21. Fracture tears and destroys blood vessels that carry nutrients to osteocytes
    2. Vascular damage initiates repair sequence
    3. Callus - specialized repair tissue that binds the broken ends of the fracture together
    4. Rapidly growing callus tissue effectively collars broken ends and stabilizes fracture so healing can proceed.

          

  4. spinal disorder (lordosis)exaggerated lumbar curve

          

  5. Bone growth & remodeling (7)1. Bones grow in length at epiphyseal plate
    2. Bones grow in diameter by the combined action of osteoclasts and osteoblasts
    3. Osteoclasts enlarge the diameter of the medullary cavity
    4. Osteoblasts from the periosteum build new bone around the outside of the bone
    5. Bone formation = bone destruction in early to middle years
    6. Remodeling activity important in homeostasis of blood calcium levels.
    7. Remodeling occurs throughout life

    women stop growing around the time of the start of their period, in case they get pregnant. don't want to compete w/baby for calcium.
    males have denser bones
