Lateral pterygoid nerve

(Redirected from External pterygoid nerve)

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]

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.
