1Major Bones of the Skull Sponge: Set up Cornell Notes on pg. 65Topic: Ch. 7 Skeletal System: Major Bones of the SkullEssential Question:Please color code each of the 7 skull bones on your skull print out AS WELL AS your notes.Ch. 7 Skeletal System:Major Bones of the Skull2.1 Atoms, Ions, and MoleculesPlease 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.
2Skull Usually consists of 22 bones All except lower jaw are firmly interlockedDivided into two parts:8 bones make up the cranium14 bones form the facial skeleton*Why do we say “usually”?
3Cranium 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.
4Cranium 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.
5Frontal boneAnterior portion of skullSuperior to Nasal cavity and eye socketsIncludes area above the eyes, forehead, roof of nasal cavity and eye sockets
6Parietal BonesBoth parietal bones are located laterally on the skullPosterior to the frontal boneForm the bulging sides and roof of the cranium
7Temporal BonesLocated laterally on both side of the skullInferior to parietal bonesHouse internal ear structures
8Occipital boneInferior to the parietal bonesPosterior to the temporal bonesForms the base of the cranium
9Facial Skeleton Forms basic shape of face 13 immovable bones 1 movable lower jaw boneProvide attachments for muscles that move the jaw and control facial expressions*Hypothesize what the functions of the facial skeleton are.
10MaxillaInferior to the frontal boneAnterior roof of mouth, floors of the orbits, sides and floor of nasal cavityAll other immovable facial bones articulate with themForm the upper jaw
11Nasal bonesAnterior to eye socketsSuperior to MaxillaLong, thin, & RectangularTwo bones fused at the midlineForm the bridge of the nose
12MandibleInferior to maxillaUsed for chewingMovableLower jawbone
13Using your notes…. Please label your skull Use the vocabulary to help youMust be done in pencilNo talking.
