Anatomical terms of neuroanatomy [ edit on Wikidata]

The lateral pterygoid nerve (or external pterygoid nerve) is a branch of the anterior division of the mandibular nerve. ^[1] It usually originates as two separate branches that travel near the buccal nerve, and enter the deep surfaces of the superior and inferior heads of the lateral pterygoid muscle. ^[2]

Nerve pathway

• trigeminal nerve (CN V)
• mandibular nerve (V3)
• anterior division of mandibular nerve

Variation

Some authors describe the lateral pterygoid nerve as a single branch of the anterior division of the mandibular nerve which then bifurcates to enter the two heads of the lateral pterygoid muscle.
