  1. Short bones
    • are about as long as they are wide (shaped like a wooden block or lego)
    • i.e the carpal bones of the wrist and the tarsal bones of teh ankle.
  2. Flat bones
    • The bone equivalant to squamos cells (wide and thin)
    • The sternum is a flat bone
  3. Irregular bones
    • a garbage category for bones that don't have any definable shape
    • Ex: the vertebrae
  4. Sesamoid bone
    • "shaped like a sesame seed"
    • a small round, flat bone 
    • cand arise as a result of trauma to muscle
    • Sometimes bones of the skull include small sesamoid bones as well.
    • the only normal example in humans is the patella.
  5. Module 9
    Graphic objective 14.  Identify the bones of the skull on a photograph or diagram.
  6. Module 9
    Graphic objective 15. Identify the bones of the vertebral column on a photograph or diagram. Compare and contrast characteristic features of cervical, thoracic, lumbar and sacral vertebrae.
  7. Module 9
    Graphic objective 16.  Identify the bones of the thorax on a photogragh or diagram.
  8. Module 9
    Graphic objective 17.  Identify the bones of the pectoral girdle and upper extremity on a photograph or diagram.
  9. Module 9
    Graphic Objective 18.  Idendify the bones of the pelvic girdle and lower extremity on a photogragh or diagram.
  10. Synarthrotic joints are
    not capable of functional movement. Perhaps the joints in your skull can move, but you really would prefer it if they didn't
  11. Amphiarthrotic joints are
    slightly moveable.  

    Sternocostal (sternum-ribs); pubic symphysis
  12. Diarthrotic joints are
    fully moveable.  The shoulder, elbow, hip, and knee joints are examples of these.
  13. Arthro- =
    Syn- =
    Amphi- =
    • joint
    • together
    • two-way
    • two
  14. What are the three classification of joints?


  15. Describe a fibrous joint
    Band of dense irregular connective tissue connects two, or bone and tooth. This is what holds together the bones of the skull; it is also what holds teeth in place.
  16. Describe a cartilaginous joint
    like that between the ribs and the sternum, is where bones are held together by cartilage.
  17. Describe a synovial joint
    a synovial cavity is present and filled with synovial fluid.  Articular cartilage covers the bones where they are in contact.  The entire structure is contained by a joint capsule.
  18. Interosseous membrane of the upper and lower extremities is functionally an
    amphiarthrotic joint
  19. Key features of a synovial joint.
    • Bones
    • -two or more articulating bones

    articular cartilage (reduces friction and provides cushion) -hyaline cartilage lining joint surface.

    • Joint capsule-fibrous capsule (outer)
    • -synovial membrane (inner)
    • -synovial fluid (secreted by membrane)
    • Bursa
    • - fluid-filled sacs near joint that help reduce friction between tendons and bone.
  20. "One" feature of synovial joints is that since they must allow for free movement, they are often __________ imperfect and subject to damage.
  21. One unique feature of the TMJ is the presence of an _______ ____, made mostly of type I collagen, halfway between the cartilaginous surfaces. This divides the synovial cavity into two parts, a ________ compartment and _______ compartment. It is this _______ ____ which, when it becomes inflamed, causes most cases of TMJ pain in patients.
    articular disc; superior; inferior; articular disc
