                              SKULL BONE PRACTICE

Name the bone (numbered) or the marking (lettered) for each part of the skull. Then
label them on the picture.

BONES OF THE CRANIUM:

   1. ___________________________ The most anterior of the 3 most superior bones
      in the body. Forms the forehead
          a. ___________________________ A tiny opening above the eye orbit that
              allows artery and nerve passage.

   2. ___________________________ A key bone of the cranium; holds all other
      bones together along the base of the skull; situated just posterior and slightly
      superior to the teeth.

   3. ___________________________ Bone that is most deeply hidden bone of the
      skull. It forms most of the bony area between the nasal cavity and the eye orbit
      (socket). Contains some sinuses.
4. ___________________________ The more posterior of the 3 most superior
   bones in the body. They form almost the whole top of the skull.
          b. ___________________________Suture that joins this bone to the
              frontal bone.




5. ___________________________ Tiny bones of the middle ear. (Not shown on
   pictures)
6. ___________________________ The most posterior bone of the skull; it also
   forms most of the base of the skull.
          c. ___________________________ Suture that attaches the parietal bone
             to this bone.
          d. ___________________________ Large opening allowing the brain
             stem to pass through to the rest of the brain.
          e. ___________________________ These condyles articulate with the
             atlas (the 1st vertebra)
          f. ___________________________ The “knot” at the very back of the
             skull. The point of many muscle attachments.
7. ___________________________ These bones (there are 2) form the area the ear
   is attached to.
           g. ___________________________ suture that joins the temporal and
               parietal bones.
           h. ___________________________ the ear canal; leads to the ear drum.
           i. ___________________________ The process just posterior to the ear;
               is attachment site for several neck muscles.
           j. ___________________________ Process that extends anteriorly to
               form the zygomatic arch; which forms the cheekbone.
FACIAL BONES AND MARKINGS:

  8. _______________________________ - The lower jaw.

              k. ____________________________ - Allows blood vessels and nerves
                 to pass from inside jaw to the outside (to lower lip skin and muscle).

              l. ____________________________ - Important condyle on posterior
                 area of mandible that articulates with the zygomatic process.

  9.    _______________________________ - These bones form middle and major part
       of face; including the upper jaw, part of eye socket, and nasal cavity walls.

              m. ____________________________ - These form anterior hard palate;
                 are part of this bone; there are 2

  10. _______________________________ - These form the cheek bones, plus part of
     eye socket (orbit).

  11. ________________________________ - Is the bridge of the nose.

  12. ________________________________ - Forms medial eye orbit wall. Is just
     beneath the tear gland and duct.
      13. ________________________________ - Is only bone in human that is not
        attached to another bone. Is suspended in mid-neck region about 2 cm above
      larynx; is attached to temporal bones by ligaments. Muscles attach here that help
     swallowing and speech. Is behind larynx.
