Mmidline prominence posterior to the foramen magnum
External Occipital Protuberance
Lateral prominence posterior to the foramen magnum
Sphenoid Bone
Bat shaped bone forming the anterior plateau of the middle cranial fossa across the width of the skull. Keystone of the cranium because it articulates with all other cranial bones.
Greater Wings
Portion of the sphenoid seen exteriorly anterior to the temporal and forming part of the eye orbits
Pterygoid processes
Inferiorly directed trough-shaped projections from the junction of the body and the greater wings.
Superior Orbital Fissures
Jagged openings in orbits providing passage for cranial nerves where they serve the eyes.
Sella turcica
A saddle shaped region in the sphenoid midline. The seat of this saddle , called hypophyseal fossa surrounds the pituitary gland.
Lesser Wings
Bat-shaped portions of the sphenoid anterior to the stella turcica
Optic Canals
Openings in the base of the lesser wing through which the optic nerve enters the orbits to serve the eyes
Foramen Rotundum
Opening lateral to the stella turcica providing passage for a branch of te V cranial nerve
Foramen Ovale
Opening posterior to the sella turcica providing passage for a branch of the fifth cranial nerve
Ethmoid Bone
Irregularly shaped bone anterior to the sphenoid. Forms the roof of the nasal cavity, upper nasal septum and part of the medial orbit walls.
Crista galli
Vertebral projection providing a point of attachment for the dura mater, helping to secure the brain within the skull
Cribriform plates
Bony plates lateral to the crista galli through which olfactory fibers pass to the brain from the nasal mucosa.
Perpendicular plate
Inferior projection of the ethmoid that forms the superior part of the nasal septum
Lateral masses
Irregularly shaped and thin-walled bony regions flanking the perpendicular plate laterally.
Superior and middle nasal conchae
Thin, delicately coiled plates of bone extending medially from the lateral masses of the ethmoid into the nasal cavity.
Mandible
The lower jawbone, which articulates with the temporal bones in the only freely movable joints of the skull
Mandibular Body
Horizontal portion; forms the chin.
Mandibular Ramus
Vertical extensions of the body on either side
mandibular condyle
Articulation point of the mandible with the mandibular fossa of the temporal bone
Coronoid Process
Jutting anterior potion of the ramus; site of muscle attachment
Mandibular angle
posterior point at which ramus meets the body
Mental Foramen
Prominent opening on the body that transmits the mental blood vessels and nerve to the lower jaw
Mandibular Foramen
Permits passage of the nerve involved with tooth sensation
Maxillae
Two bones fused in a median suture; forming the upper jaw and part of the orbits. Connects to all facial bones except maxillae.
Aveolar Margin
Inferior margin containing sockets in which teeth lie.
Palatine processes
Forms the anterior hard palate; meet medially in the intermaxillary suture.
Infraorbital foramen
Opening under the orbit carrying the infraorbital nerves and blood vessels to the nasal region.
Incisive fossa
Large bilateral opening located posterior to the central incisor tooth of the maxilla and piercing the hard palate
Lacrimal Bone
