8 bones of the face
Inferior nasal conchae
4 features of the orbit
Supraorbital foramen or notch
Supraorbital and infraorbital fissure
3 boundaries of the nasal cavity
(vomer and perpendicular plate of ethmoid)
5 features of the mandible
Condyloid process (TMJ)
Ramus, body and angle
Nerve located in upper nasal cavity and travels through the cribiform plate (transmits gaseous impulses to olfactory cortex)
CN I (olfactory nerve-sensory)
Sensory nerve that senses sight and travels through the optic canal, enters the back of the eye and transmits light impulses to the visual cortex)
CN II (optic nerve)
Motor nerve that elevates, depresses and adducts the eye and travels through the superior orbital fissure (pupillary constrictor muscle)
CN III (oculomotor nerve)
Motor nerve that rotates the eye down and out and travels through the superior orbital fissure (superior oblique muscle)
CN IV (trochlear nerve)
Sensory and motor nerve that provides sensation and mastication to the face and separates into 3 divisions while traveling through 7 foramina
CN V (trigeminal nerve)
Sensory nerve providing sensation to the upper face and eye traveling through the superior orbital fissure and supraorbital foramen/notch
CN V1 (opthalmic nerve)
Sensory nerve that provides sensation to the middle of the face and upper teeth and travels through the foramen rotundum and infraorbital foramen
CN V2 (maxilla nerve)
Sensory and motor nerve providing sensation to the lower face, lower teeth and anterior 2/3 of tongue and mastication traveling through the foramen ovale, mandibular foramen and mental foramen
CN V3 (mandibular nerve)
Motor nerve that abducts the eye and travels through the superior orbital fissure (lateral rectus muscle)
CN VI (abducens nerve)
Sensory and motor nerve that provides sensation to the anterior 2/3 tongue and facial expression; para/sympathetic to lacrimal and salivary glands traveling through the internal acoustic meatus and stylomastoid foramen
CN VII (facial nerve)
Sensory nerve providing hearing and equilibrium and travels through the internal acoustic meatus innervating semicircular canals and cochlea transmitting sound impulses to auditory cortex
CN VIII (vestibulocochlear nerve)
Sensory and motor nerve that provides taste and sensory to posterior 1/3 of tongue and pharynx muscle (stylopharyngeus); para/sympathetic to parotid gland traveling through the jugular foramen
CN IX (glossopharyngeal nerve)
Sensory and motor nerve to the organs of the neck, thorax and abdomen (para/sympathetic) traveling through the jugular foramen
CN X (vagus nerve) widest distribution
Motor nerve innervating trapezius and sternocleidomastoid muscles traveling through foramen magnum
CN XI (accessory nerve)
