TRIGEMINAL NERVE
MAXILLARY NERVE
ZYGOMATIC NERVE
8. Zygomatic nerve

a. Enters the orbit through the inferior orbital fissure and divides into
the zygomaticofacial and zygomaticotemporal nerves

b. Zygomaticofacial nerve: enters a zygomatico-orbital foramen and
emerges from the zygomaticofacial foramen to supply the skin over-
lying the lateral surface of the zygomatic bone

c. Zygomaticotemporal nerve: gives off a branch containing postgan-
glionic parasympathetic secretomotor fibers from the pterygopalatine
ganglion to the lacrimal nerve; it then enters a zygomatico-orbital
foramen and emerges from the zygomaticotemporal foramen to sup-
ply the skin of the anterior part of the temple
TRIGEMINAL NERVE
MAXILLARY NERVE
PHARYNGEAL BRANCH
9. Pharyngeal branch: courses posteriorly through the palatovaginal ca-
nal and provides sensory innervation to the mucosa of the nasopharynx
MANDIBULAR NERVE
C. Mandibular nerve

1. Emerges through foramen ovale, deep to the lateral pterygoid, and breaks
up into the sensory and motor branches noted below
MANDIBULAR NERVE

NERVE TO MEDIAL PTE.
C. Mandibular nerve

2. Nerve to the medial pterygoid: gives rise to the nerve to the tensor
tympani and the nerve to the tensor veli palatini, and then penetrates
the deep surface of the medial pterygoid, innervating it
MANDIBULAR NERVE

MASSETERIC NERVE
C. Mandibular nerve

3. Masseteric nerve: emerges superior to the lateral pterygoid and then
passes laterally through the mandibular notch to supply the masseter
MANDIBULAR NERVE

DEEP TEMPORAL NERVES
C. Mandibular nerve

4. Deep temporal nerves: the anterior deep temporal and posterior deep
temporal nerves emerge between the two heads of the lateral pterygoid
and superior to the lateral pterygoid, respectively; they ascend in the
temporal fossa and innervate the temporalis
MANDIBULAR NERVE

NERVE TO THE LATERAL PTE.
C. Mandibular nerve

5. Nerve to the lateral pterygoid: penetrates the deep surface of the lateral
pterygoid, innervating it
MANDIBULAR NERVE

BUCCAL NERVE
C. Mandibular nerve

6. Buccal nerve: emerges between the two heads of the lateral pterygoid;
some branches supply the skin of the cheek and others penetrate the
buccinator to provide sensory innervation to the mucosa of the cheek
MANDIBULAR NERVE

AURICULOTEMPORAL NERVE
7. Auriculotemporal nerve

a. Courses posteriorly, deep to the lateral pterygoid; emerges posterior
to the neck of the mandible and gives off postganglionic parasympa-
thetic secretomotor fibers from the otic ganglion to the facial nerve

b. Ascends between the auricle and superficial temporal artery and pro-
vides sensory innervation to the auricle, external acoustic meatus,
tympanic membrane, and posterior part of the temple
