9

cranial bones

surrounds and protects the brain

10

frontal sinuses

air-filled chambers that open into the nasal cavities

11

temporal bone

articulates with mandible, protects sense organs of inner ear

12

petrous portion

"peaks", surrounds and protects ear organs

13

squamous portion

smooth, flat surface

14

mandibular fossa

forms temporal mandibular joint

15

zygomatic process

forms zygomatic arch (cheek bone)

16

mastoid process

attachment site for muscles that move the head

17

styloid process

"stylus", attachment for ligaments

18

external acoustic meatus

auditory canal, leads to inner ear organs

19

sphenoid bone

acts as a bridge between cranial and facial bones

20

sella turcica

"turkish saddle", cradles pituitary gland

21

ethmoid bone

irregularly shaped, forms part of orbit, floor of cranium and roof of nasal cavity

22

axial skeleton

framework that supports and protects organs in body cavities
