Occipital protuberance

Back 11

Springboard for the fleshy contour of the neck

Front 12

Parietals

Back 12

Lie between frontal and occipital bones and form the upper side wall and rear vaulted roof of the skull

Front 13

Parietal eminence

Back 13

Point of greatest convexity in each parietal

Front 14

Temporals

Back 14

Form the lower side walls of the cranium in the region of the ear

Front 15

Zygomatic arch

Back 15

Project forward from each temporal to join the zygomatic bone (cheekbone) in the front

Front 16

Mastoid process

Back 16

Bulges downward to the rear of the 'ear hole'

Front 17

Styloid process

Back 17

A slender spur below the 'ear hole'

Front 18

Sphenoid

Back 18

Single bone that straddles the undersurface of the cranium, appearing in both side walls between the temporal and frontal bones at the regions known as the temples

Front 19

Cranial sutures

Back 19

Ragged edges that allow the bones of the cranium to fit tightly into each other

Front 20

Temporal line

Back 20

Arises from the outer end of the brow ridge and arches backward over the cranium

Front 21

Temporal fossa

Back 21

The hollow side wall of the temporal that is filled with jaw muscle

Front 22

Face

Back 22

14 bones that hand like a mask from beneath the small forward end of the ovoid cranium

Front 23

Zygomatic bones

Back 23

Cheekbones; prominent angular plates that fasten wing-like to the upper jaw and creat a 'balcony above the lower jaw

Front 24

Nasal bones

Back 24

Project less than an inch from beneath the wedge between the orbits

Front 25

Maxillae

Back 25

Jawbones; constitute the chief body of the upper jaw, give root to the teeth, and enter into the formation of the cheeks laterally and the wall of the nose above

Front 26

Canine fossa

Back 26

Where each maxilla sinks inward below the orbit (filled with cheek muscle)

Front 27

Nasal spine

Back 27

Pointed spur where the two maxillae join at the base of the inverted-heart-shaped nasal cavity

Front 28

Dental arch

Back 28

Where the teeth are socketed

Front 29

Hard palate

Back 29

Roof of the mouth

Front 30

Mental tubercles

Back 30

Small lumps at either side of the midline that give squareness to the chin (said to be most distinct in males)

Front 31

Ramus

Back 31

A broad, thin, blade that springs upward from the back of the jaw

Front 32

Angle of the mandibular

Back 32

Described by the lower border of the body and the rear border of the ramus; approximates 120 degrees

Front 33

Coronoid process

Back 33

Forward division of the ramus for attachment of the temporalis muscle of mastication

Front 34

Condyloid process

Back 34

Rear division of the ramus for articulation with the skull in the temporal bone at the front of the 'ear holes' (hinge joint)
