It belongs to the muscles of mastication (chewing muscles) and is involved in the movements of the temporomandibular joint (TMJ). Like the other mastication muscles, the lateral pterygoid muscle is innervated by the trigeminal nerve, more precisely the lateral pterygoid nerve from the mandibular nerve. The muscle has two heads: a superior and an inferior head, with different origins and insertions. In this video tutorial we will go over the most important anatomical facts about this chewing muscle including its origin, insertion, nerve supply and functions. 0:08 introduction to the pterygoid muscles 0:25 origin and insertion of superior head 0:40 origin and insertion of inferior head 0:54 nerve supply by the lateral pterygoid nerve 1:04 function: opening the jaw 1:29 function: unilateral and bilateral contraction Want to test your knowledge on the muscles of mastication?
