External Pterygoid Nerve (or lateral pterygoid nerve): The nerve to the Pterygoideus externus frequently arises in conjunction with the buccinator nerve, but it may be given off separately from the anterior division of the mandibular nerve.

It enters the deep surface of the muscle.

ophthalmic (V1)

frontal: supratrochlear - supraorbital (lateral branch, medial branch)

lacrimal

maxillary (V2)

in meninges	middle meningeal

in pterygopalatine fossa	zygomatic (zygomaticotemporal, zygomaticofacial) - pterygopalatine (pterygopalatine ganglion see below for details) - posterior superior alveolar

in infraorbital canal	infraorbital nerve: superior alveolar (middle, anterior) - internal nasal branches

on face	inferior palpebral - external nasal - superior labial (infraorbital plexus)

mandibular (V3)

in meninges	meningeal

anterior	to muscles of mastication (medial pterygoid/to tensor veli palatini, lateral pterygoid, masseteric, deep temporal) - buccal
