skull bones

parietal

forms the upper sides and roof of skull

nasal

smal paired bones that form the bridge of nose

sphenoid

a complex bone near the center of the skull base behind the eyes

temporal

on sides and base of skull around ears

ethmoid

between the eyes forming part of nasal cavity, nasal septum and medial walls of eye sockets

lacrimal

tiny bone on the inner wall of each eye socket close to tear duct

zygomatic

cheekbone

infraorbital foramen

small opening in the maxilla (upper jaw) just below the eye socket

maxilla

upper jaw bone

mandible

lower jaw bone

mental foramen

small opening on each side of mandible (lower jaw) near the chin

frontal bone

forms forehead and upper part of eye sockets

glabella

smooth area of frontal bone between eyebrows just above the rbidge of nose

supraorbital foramen

an opening along the upper edge of eye socket in frontal bone

vomer

thin, pillow shaped bone that forms the lower and back portion of nasal septum separating the nasal passages

lambdoid suture

separates the parietal and occipital bone

occipital

forms back and much of base of the skull

external occipital protuberance

bump on back of skull near the midline

occipital condyle

one of the smooth rounded surfaces on the underside of the occipital bone that articulates with the atlas (next to foramen magnum)

sagittal suture

runs front to back along top midline of the skull separating the two parietal bones

coronal suture

runs from sides to side across top of skull separating frontal bone from parietal bones

squamous suture

separates parietal and temporal bones

zygomatic process

projection of temporal bone that extends forward to join the zygomatic bone

external acoustic meatus

the opening of the ear canal in the temporal bone

mastoid process

a rounded projection of the temporal bone just behind and below the ear opening

styloid process

a thin, pointed projection extending downward from the temporal bone, below the ear region

condylar process

the rounded upper- back projection of the mandible that meets the temporal bone to form the jaw joint

alveolar processes

the tooth bearing ridges of the maxilla and mandible that contain tooth sockets

coronoid process

the pointed front upper projection of the mandible’s ramus. It provides attachment for a chewing muscle

sella turcica of sphenoid bone

a saddle-shaped depression in the sphenoid bone that houses the pituitary gland

palatine bone

paired bones that form the back portion of the hard palate and contribute to the nasal cavity and eye sockets

crista galli

a vertical, crest-like projection of the ethmoid bone inside the skull, where a membrane supporting the brain attaches
