Frontal
Top of head and forehead
Nasal
Bridge of nose
Maxilla
Between nostrils and upper row of teeth
Mandible
Lower jaw
Zygomatic-Malar
Cheek bone
Temporal
Side of head, behind ear
Sphenoid
Behind cheek bone, next to Temporal
Ethmoid
Between nostrils, below bridge of nose
Lacrimal
In between eyes, next to tear ducts, either side of upper bridge of nose
Vomer
Base of nose structure, below Ethmoid bone
Palatine
Pallet of mouth
Conchae
Inside nasal cavity, above pallet
Glabella
Mid-forehead, between eyes, small, circular
Alveolar Process of Maxilla
Base of Maxilla, made up of cavities for teeth
Inferior Nasal Concha

Mental Protuberance
Chin
Mandibular Symphysis
Vertical ridge between teeth and chin
Alveolar process of Mandible
Top of lower jaw that contains cavities for teeth
Coronoid Process of Mandible
Top of jaw closest to front of face, where temporalis muscle connects
Mental Foramen
Two openings on either side of the Mandible that allows for nerves to exit skull
Mandibular Fossa
Top of jaw, near base of ear, involved in chewing
Mandibular Condyle
Determines growth of Mandible, located back upper jaw, just below Mandibular Fossa
Canines
Teeth at four corners of front of mouth, long and sharp
Molars
Back teeth (12)
Occipital Protuberance
Bump on lower back center of head
Occipital Condyle
Base of skull, on either side of opening for brain-stem, allows side to side movement of skull
Cribiform Plate of Ethmoid
Small bone above nasal cavity, passage for olfactory nerves
Zygomatic Arch
Arch-like bone from Temporal bone to Zygomatic, around base of ear and top of jaw bone
Zygomatic Process of Frontal
Part of Frontal bone that extends down from outer side of eye socket
Zygomatic Process of Maxilla
Gives structure to cheek, along nose, small
Zygomatic Process of Temporal
Above top of jaw bone, behind Zygomatic bone, attachment point for temporal fascia
Styloid Process of Temporal
Just below ear, stick like protuberance
Crista Galli
Internal plate of ethmoid bone, above Cribiform Plate
External Auditory Meatus
Shaft between external ear and inner ear
Greater Wing of the Sphenoid
Butterfly shaped bone directly in the center of the skull
Incisive Foramen
Small area on mouth pallet directly behind front two teeth
Incisors
Middle four teeth, upper and lower
Infraorbital Foramen
Middle of cheek bone
Lambdoidal Suture
Cranial suture between Occipital and Parietal bone, mid-back of head
Lesser wing of Sphenoid
Sphenoid wing closer to front of face, center of skull
Median Palatine Suture
Suture in the middle of the mouth pallet
Mastoid Process
Base of skull behind ear and down, responsible for protecting some inner ear processes, muscle attachment point and pressure regulation
Supraorbital Foramen
Located on the inner top of the eye socket, allows for nerve passage
Trochlea
Ligamentous sling above the eyeball
Premolars
Teeth directly behind canines (8 total)
Optic Foramen
Circular hole in back of eye socket, allows for nerve passage
Foramen Magnum
Opening at base of skull for brain stem
Foramen Ovale
Two holes just behind end of bottom row of teeth in middle of skull, on sphenoid bone, conducts nerves and arteries
Horizontal Plate of Palatine
Farthest back portion of mouth pallet
Palatine Process of Maxilla
Thick, horizontal bone that makes up 3/4 of mouth pallet
Sella Turcica
Middle depression in Sphenoid bone, contains pituitary gland, internal, “saddle”, in ear
Angle of Mandible
Corner the jawbone makes
