5 Written questions

5 Matching questions

  1. short bones
  2. fact: spongy bone and marrow cavities lighten the heavy skeleton and provide room for the bone marrow
  3. endosteum
  4. intramembranous ossification
  5. osteomalacia
  1. a thinner connective tissue membrane that covers internal bone surfaces
    - covers the trabeculae of spongy bone
    - lines the central canals of osteons
    - is osteogenic, containing both osteoblasts and osteoclasts
  2. b (blank)
  3. c roughly cube-shaped
    - occur in the wrist and ankle
  4. d applies to a number of disorders in adults in which the bones are inadequately mineralized
    - even though osteoid matrix is produced, calcification does not occur, and the bones soften and weaken
    - main symptom: pain when weight is put on the affected bone
    - caused by inadequate amounts of vitamin D or calcium phosphate in the diet
    - cured by drinking vitamin D-fortified milk and exposing the skin to sunlight
  5. e membrane bones form directly from mesenchyme without first being modeled in cartilage
    - all bones of the skull, except a few at the base of the skull, are of this category
    - the clavicles (collarbones) are the only bones formed by intramembranous ossification that are not in the skull

5 Multiple choice questions

  1. special type of short bone that forms within a tendon
    - ex: kneecap/patella
    - vary in size and number
    - some clearly act to alter the direction of pull of a tendon
    - others reduce friction and modify pressure in tendons, thus reducing abrasion or tearing
  2. chondroblasts at the "top" of the stack that divide quickly, pushing the epiphysis away from the diaphysis, thereby causing the entire long bone to lengthen
  3. like osteomalacia for kids
    - more severe than osteomalacia
    - caused by inadequate amounts of vitamin D or calcium phosphate in the diet
    - cured by drinking vitamin D-fortified milk and exposing the skin to sunlight
  4. diaphysis
    epiphyses
    blood vessels
    medullary cavity
    membranes
  5. canal that runs through the core of each osteon
    - lined by endosteum
    - contains its own blood vessels, which supply nutrients to the bone cells of the osteon, and its own nerve fibers
    - endosteum that lines the central canal is an osteogenic layer
    - unlike the growth rings in trees, lamellae of bone tissue are added to the inner surface of the osteon, thus decreasing the diameter of the central canal

5 True/False questions

  1. interstitial lamellaesimilar to hyaline cartilage; matrix contains many elastic fibers along with the delicate collagen fibrils; more elastic than hyaline cartilage & better able to tolerate repeated bending; epiglottis and outer ear

          

  2. diploeinternal spongy bone in flat bones

          

  3. intramembranous ossification process(1) a bone collar forms around the diaphysis
    (2) cartilage calcifies in the center of the diaphysis
    (3) periosteal bud invades the diaphysis, and the first bone trabeculae form; by the third month of development, bone tissue continues to form around the diaphysis from the periosteum and has begun to appear in the center of the diaphysis; this bone tissue makes up the primary ossification center
    (4) diaphysis elongates, and the medullary cavity forms; areas of bone formation in the epiphyses are called secondary ossification centers; larger long bones of the body can have several ossification centers in each epiphysis
    (5) epiphyses ossify, and cartilaginous epiphyseal plates separate diaphysis and epiphyses

          

  4. epiphyseslike osteomalacia for kids
    - more severe than osteomalacia
    - caused by inadequate amounts of vitamin D or calcium phosphate in the diet
    - cured by drinking vitamin D-fortified milk and exposing the skin to sunlight

          

  5. when we are physically active...(1) hematoma formation
    (2) fibrocartilaginous callus formation
    (3) bony callus formation
    (4) bone remodeling
