Skull and facial bones and features

Temporal bone

Sphenoid bone

Ethmoid bone

Palatine

Lacrimal

Zygomatic

inferior nasal conchae

Vomer

supraorbital foramen of frontal bone

coronal suture of parietal bone

the suture between the parietal and frontal bones of the skull

sagittal suture of parietal bone

Located on the midline of the skull lies between both parietal bones (immovable joint)

external occipital protuberance of occipital bone

bump on back of head

occipital condyles of occipital bone

Rounded projections lateral to the foramen magnum that articulate with the first cervical vertebra (atlas)

jugular foramen

found along the suture between occipital and temporal bone

lambdoidal suture

between occipital and parietal bones

carotid foramen, Temporal bone

opening for carotid artery

external auditory meatus, temporal bone

hole in the temporal bone extending medially to the inner ear

internal auditory meatus, temporal bone

Passageway for nerves and vessels that supply the ear.

mandibular fossa

the depression in the temporal bone into which the condyle of the mandible fits

mastoid process of temporal bone

round projection on the temporal bone behind the ear

petrous portion of temporal bone

part of the temporal bone located at the floor of the cranial cavity contains the inner ear

foramen lacerum of temporal bone

temporal, sphenoid, and occipital bones join and create this opening in the middle

squamous portion of temporal bone

largest part of the temporal bone and is flat and located superiorly. The outer facing surface of the squamous bone is convex in shape, forming part of the temporal fossa

squamous suture of the parietal and temporal bone

Between parietal and temporal bones

styloid process of temporal bone

pole-like process extending downward from the temporal bone on each side of the skull

zygomatic process of temporal bone

a projection of the temporal bone that forms part of the zygoma. The zygomatic arch (cheek bone) is formed by the zygomatic process of temporal bone and the temporal process of the zygomatic bone, the two being united by an oblique suture

zygomatic process

Olfactory foramina of the cribriform plate

olfactory foramina allow passage nerve fibers that make up the olfactory nerve. necessary for the human sense of smell

crista galli of ethmoid bone

superior projection in the middle of the cribriform plate of the ethmoid bone; providing a point of attachment for the dura mater, helping to secure the brain within the skull

perpendicular plate of ethmoid bone

superior portion of the bony nasal septum

middle turbinate/nasal conchae

Catches sinus drainage, warms, humidifies and filters air inhaled into the nose.

ethmoidal sinuses of ethmoid bone

air cells

greater wing of sphenoid bone

lesser wing of sphenoid bone

optic foramen of sphenoid bone

foramen rotundum of sphenoid bone

foramen ovale of sphenoid bone

Oval shaped. Almost the most lateral set.

foramen spinosum of sphenoid bone

opening through which blood vessels pass that feed membranes surrounding the CNS

pterygoid process of sphenoid bone

arises at junction of greater wing and body of the sphenoid, only seen on inferior surface of skull

sella turcica of sphenoid bone

houses the pituitary gland

sphenoidal sinuses of the sphenoid bone

empty large spaces deep to nose (away from skull)

superior orbital fissure of sphenoid bone

Between greater and lesser wing on the sphenoid bone, transmits oculomotor, trochlear, and abducens nerves. Also a branch of opthalmic CN V1

temporal process of zygomatic bone

points posteriorly and articulates with the zygomatic process of the temporal bone. This bone and bone feature forms the other half of the zygomatic arch

alveolar process of maxilla

curved, inferior margin of the maxilla that supports and anchors the upper teeth

inferior orbital fissure of maxilla

maxillary and sphenoid bone

palatine process of maxilla

comprises anterior ~3/4 of hard palate)

horizontal plate of palatine bone

posterior 1/4 of hard palate

alveolar process of mandible

supports the lower teeth

mandibular foramen of mandible

Located on the medial surface of each ramus; passageway for the nerve involved in tooth sensation. (Dentists inject anesthetic into this foramen before working on the lower teeth)

mental foramen of mandible

one of two holes located on the anterior surface of the mandible. It permits passage of the mental nerve and vessels.

mandible angle

where the body and ramus of the mandible meet

mandible ramus

vertical portion of the mandible

condylar process of mandible

thickened upward projection from posterior margin of mandibular ramus

coronoid process of mandible

insertion of temporalis

mandibular notch of mandible

depression between the condylar process and the coronoid process

anterior fontanel

Anterior side of the skull

in baby where the sagittal suture and coronal suture meet

frontal suture of fetal skull
