MANDIBULAR NERVE

NERVE TO THE MEDIAL PTERYGOID
2. Nerve to the medial pterygoid: penetrates the deep surface ofthe me-
dial pterygoid, innervating it; gives rise to the nerve to the tensor
tympani and the nerve to the tensor veli palatini
MANDIBULAR NERVE

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

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

NERVE TO LATERAL PTERYGOID
5. Nerve to the lateral pterygoid: penetrates the deep surface ofthe lateral
pterygoid, innervating it
MANDIBULAR NERVE

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

7. Auriculotemporal nerve

COURSES...
7. Auriculotemporal nerve

a. Courses posteriorly, deep to the lateral pterygoid; emerges poste-
rior to the neck ofthe mandible and gives off postganglionic para-
sympathetic secretomotor fibers from the otic ganglion to the facial
nerve
MANDIBULAR NERVE

7. Auriculotemporal nerve

ASCENDS B/W...
b. Ascends between tlie auricle and superficial temporal artery and pro-
vides sensory innervation to the auricle, external acoustic meatus,
and posterior part of the temple
MANDIBULAR NERVE

LINGUAL NERVE

DESCENDS DEEP TO...
8. Lingual nerve

a. Descends deep to the lateral pterygoid and appears along its infe-
rior border; after coursing anteriorly on the lateral surface of the
medial pterygoid, the lingual nerve provides general sensory inner-
vation to the anterior two-thirds ofthe tongue
MANDIBULAR NERVE

LINGUAL NERVE

PROXIMALLY IT IS JOINED BY...
b. Proximally, it isjoined on its posterior aspect by the chorda tympani
nerve, a branch ofthe facial nerve which contains taste fibers for the
anterior two-thirds ofthe tongue and preganglionic parasympathetic
fibers for synapse in the submandibular ganglion
MANDIBULAR NERVE

INFERIOR ALVEOLAR NERVE
9. Inferior alveolar nerve

a. Descends deep to the lateral pterygoid and appears along its infe-
rior border, posterior to the lingual nerve; it then courses toward the
mandibular foramen on the lateral surface ofthe medial pterygoid,
inferior to the lingual nerve
