Ch. 7 Skeletal System:
Major Bones of the Skull
2.1 Atoms, Ions, and Molecules
Please color code each of the 7 skull bones on your skull print out AS WELL AS your notes.
Ex: If you color the Frontal bone purple, you need to underline/box/highlight the Frontal bone section of your notes.

2. Skull Usually consists of 22 bones
All except lower jaw are firmly interlocked
Divided into two parts:
8 bones make up the cranium
14 bones form the facial skeleton
*Why do we say “usually”?

3. Cranium is billed as "The Game for Your Whole Brain."
How many of you have heard the word cranium?
At your table hypothesize what the cranium’s function is.
Cranium is billed as "The Game for Your Whole Brain."
Unlike many other party games, Cranium includes a wide variety of activities.

4. Cranium Functions: Encloses and protects the brain
Attachments for muscles that make chewing and head movements possible
*Predict what would happen to your brain if you had a major cranium injury.

5. Frontal bone
Anterior portion of skull
Superior to Nasal cavity and eye sockets
Includes area above the eyes, forehead, roof of nasal cavity and eye sockets

6. Parietal Bones
Both parietal bones are located laterally on the skull
Posterior to the frontal bone
Form the bulging sides and roof of the cranium

7. Temporal Bones
Located laterally on both side of the skull
Inferior to parietal bones
House internal ear structures

8. Occipital bone
Inferior to the parietal bones
Posterior to the temporal bones
Forms the base of the cranium

9. Facial Skeleton Forms basic shape of face 13 immovable bones
1 movable lower jaw bone
Provide attachments for muscles that move the jaw and control facial expressions
*Hypothesize what the functions of the facial skeleton are.

10. Maxilla
Inferior to the frontal bone
Anterior roof of mouth, floors of the orbits, sides and floor of nasal cavity
All other immovable facial bones articulate with them
Form the upper jaw

11. Nasal bones
Anterior to eye sockets
Superior to Maxilla
Long, thin, & Rectangular
Two bones fused at the midline
Form the bridge of the nose

12. Mandible
Inferior to maxilla
Used for chewing
Movable
Lower jawbone

16. Skeleton Typogram Draw a skeleton using only your vocabulary
Make sure the bones are in the correct places!
Spelling counts
After the skeleton is drawn you may be as creative as you wish
