Sponge: Set up Cornell Notes on pg. 65 Topic: Ch. 7 Skeletal System: Major Bones of the Skull Essential Question: 1.Please color code each of the 7 skull bones on your skull print out AS WELL AS your notes. 2.1 Atoms, Ions, and Molecules 1.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. Ch. 7 Skeletal System: Major Bones of the Skull
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." Unlike many other party games, Cranium includes a wide variety of activities. How many of you have heard the word cranium? At your table hypothesize what the cranium’s function is.
4 Cranium Encloses and protects the brain Attachments for muscles that make chewing and head movements possible Functions: *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
Using your notes…. 13 Please label your skull Use the vocabulary to help you Must be done in pencil No talking.

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
