  1. when we are incapacitated...
  2. compound
  3. osteogenesis
  4. healing of a simple fracture
  5. medullary cavity
  1. a - filled with yellow bone marrow
    - very center of the diaphysis that contains no bone tissue at all
    - aka marrow cavity
  2. b bone is resorbed because it is not needed to support the body
  3. c (1) hematoma formation
    (2) fibrocartilaginous callus formation
    (3) bony callus formation
    (4) bone remodeling
  4. d begins in the embryo, proceeds through childhood and adolescence as the skeleton grows, and then occurs at a slower rate in the adult as part of a continual remodeling of the full-grown skeleton
  5. e broken ends of the bone prodtrude through the skin

5 Multiple choice questions

  1. incomplete lamellae that lie between the osteons
    - remains of old osteons that have been cut through by bone remodeling
    - extends around the entire circumference of the diaphysis
  2. main vessels serving the diaphysis
    - together run through a hole in the wall of the diaphysis, the nutrient foramen
  3. develop from a mesenchymal membrane through a process called intramembranous ossification
  4. most abundant; provides support through flexibility and resilience; makes up the articular cartilage that covers the ends of adjoining bones in movable joints; forms the cartilaginous attachments of the ribs to the sternum; accounts for most of the cartilage found in the respiratory structures; forms the embryonic skeleton
  5. also called growth plates
    - responsible for lengthening the bones during the two decades following birth

5 True/False questions

  1. blood vesselslonger than they are wide
    - has a shaft and two distinct ends


  2. structure of short bones- similar to long bones, but have no diaphysis
    - contain bone marrow (between the trabeculae of their spongy bone), but no marrow cavity is present


  3. osteogenesis, before week 8skeleton of the human embryo consists only of hyaline cartilage and some membranes of mesenchyme, an embryonic connective tissue
    - bone tissue first appears in week 8 and eventually replaces most cartilage and mesenchymal membranes in the skeleton


  4. epiphyseal linebetween 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


  5. osteocyteswhen 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
