5 Written questions

5 Matching questions

  1. fact: trabeculae of spongy bone seem to align along stress lines in an organized pattern of tiny struts
  2. periosteal bud
  3. structure of short bones
  4. deep layer (periosteal membrane)
  5. epiphyseal line
  1. a between the dipahysis and each epiphysis of an adult long bone
    - line is a remnant of the epiphyseal plate, a disc of hyaline cartilage that grows during childhood to lengthen the bone
  2. b osteogenic, containing bone-depositing cells (osteoblasts) and bone-destroying cells (osteoclasts)
    - indistinguishable from the fibroblasts within this layer
  3. c consists of a nutrient artery and vein, along with the cells that will form the bone marrow
    - contains bone-forming and bone-destroying cells (osteogenic stem cells and osteoclasts)
  4. d (blank)
  5. e - similar to long bones, but have no diaphysis
    - contain bone marrow (between the trabeculae of their spongy bone), but no marrow cavity is present

5 Multiple choice questions

  1. shaft
    forms the long axis of a long bone
  2. thin, flattened, and usually somewhat curved
    - most cranial bones of the skull, ribs, sternum, scapula
  3. bone is resorbed because it is not needed to support the body
  4. (1) hematoma formation
    (2) fibrocartilaginous callus formation
    (3) bony callus formation
    (4) bone remodeling
  5. every 3 or 4 years

5 True/False questions

  1. epiphyseal platesbetween the dipahysis and each epiphysis of an adult long bone
    - line is a remnant of the epiphyseal plate, a disc of hyaline cartilage that grows during childhood to lengthen the bone

          

  2. Perforating canals (Volkmann's canals)- thick bundles of collagen that run from the periosteum into the bone matrix
    - what secures the periosteum to the underlying bone

          

  3. bone resorptionaccomplished by osteoclasts

          

  4. osteoporosiswhen osteoblasts are completely surrounded by bone matrix and are no longer producing new osteoid
    - function to keep the bone matrix healthy
    - if osteocytes die or are destroyed, the bone matrix is resorbed

          

  5. canaliculieach of the tubes in an osteon
    - layer of bone matrix in which the collagen fibers and mineral crystals align and run in a single direction
    - fibers and crystals of adjacent lamellae always run in roughly opposite directions; alternating pattern is optimal for withstanding torsion, or twisting, stresses
    - also inhibiting crack propagation: when a crack reaches the edge of a lamella, the forces causing the crack are dispersed around the lamellar boundaries, thus preventing the crack from progressing into deeper parts of the bone and causing fracture
