CN III. Oculomotor Nerve
Motor to most striated muscles of the eye (superior
rectus, medial rectus, inferior rectus, inferior oblique, and
levator palpebrae superioris; i.e. all extra ocular muscles
except the superior oblique and lateral rectus muscles).
Visceral motor (parasympathetic) to two smooth muscles
of the eye (ciliaris and sphincter pupillae). Parasympathetic preganglionic fibers synapse at the ciliary ganglion;
postganglionic branches travel with the ciliary branches of
the ophthalmic division of the trigeminal nerv (CN V1). T

and underlying deep face including the sphenoid and
ethmoid paranasal sinuses.

Intermediate Nerves
CN V3. Trigeminal nerve, Mandibular Division
Challenging Nerves
CN VII. Facial Nerve
CN V3. Trigeminal nerve,
Mandibular Division
Motor to the muscles of mastication (temporalis, masseter,
lateral pterygoid, medial pterygoid), tensor tympani, tensor
veli palatini, mylohyoid, and the anterior belly of digastricus.
General sensation from the lower part of the face, lower jaw,
oral part of the tongue, and floor of the oral cavity.
Foramen ovale
Infratemporal fossa
Mandibular foramen (inferior alveolar br.)

CN VII. Facial Nerve
Motor to the stapedius, stylohyoid, and posterior belly of
digastricus muscles, and to all muscles of facial expression.
Visceral motor (parasympathetic) to the lacrimal, nasal, and
palatine glands. Preganglionic fibers in the greater petrosal
branch synapse at the pterygopalatine ganglion; postganglionic fibers distribute with branches of the maxillary nerve
(CN V2). T
Visceral motor (parasympathetic) to the submandibular,
sublingual, and minor salivary glands of the oral cavity. Preganglionic fibers in the chorda tympani branch synapse at
the submandibular ganglion; postganglionic fibers distribute
with branches of the mandibular nerve (CN V3). T
Internal acoustic meatus
Stylomastoid foramen (motor branches)
Greater petrosal hiatus
Petrotympanic fissure (chorda tympani)
Special sensation (taste) from the palate (greater petrosal
branch). Special sensation (taste) from the oral part of the
tongue (chorda tympani branch).

Challenging nerves
CN IX. Glossopharyngeal nerve
Challenging Nerves
CN X. Vagus Nerve,
CN IX. Glossopharyngeal
nerve
Motor to the stylopharyngeus muscle.
Visceral motor (parasympathetic) to the parotid salivary
gland. Preganglionic fibers in the lesser petrosal nerve
synapse at the otic ganglion; postganglionic fibers
distribute with the auriculotemporal branch of the
mandibular division of the trigeminal nerve (CN V3).
General sensation from the superior half of the epiglottis
and all visceral compartment structures superior to the
epiglottis.
Jugular foramen
Lesser petrosal hiatus
Visceral sensation from the carotid sinus (baroreception)
and carotid body (chemoreception).
Midsagittal section
Special sensation (taste) from the visceral part of the
tongue.
CN X. Vagus Nerve
Motor to the muscles of the palate (levator veli palatini, musculus uvuli, palatoglossus, and palatopharyngeus; i.e. all palatal
muscles except tensor veli palatini). Motor to the muscles of the
pharynx (superior, middle, and inferior constrictor, palatopharyngeus; and salpingopharyngeus; i.e. all pharyngeal muscles
except stylopharyngeus (CNIX). Motor to the striated muscle of
the upper esophagus. Motor to all muscles of the larynx.
Visceral motor (parasympathetic) to smooth muscle and glands
of the respiratory system and gastrointestinal tract proximal to
the splenic flexure of the colon.
General sensation from the inferior half of the epiglottis and all
visceral compartment structures inferior to the epiglottis.
Jugular foramen
Special sensation (taste) from the base of the epiglottis.
Midsagittal section
Visceral sensation from the inferior half of the epiglottis and all
visceral compartment structures inferior to the epiglottis.
