Buccinator muscle

In this article we will discuss about the Buccinator muscle. So, let’s get started.

It originates from the outer surface of the alveolar processes of maxilla and mandible, buccinator crest, and from the anterior border of pterygomandibular raphe and gets inserted into the angle of mouth penetrating into the orbicularis oris muscle. It is innervated by the buccal branch of facial nerve and artery supply is through the buccal artery. It’s chief action is mastication (pull back the angle of mouth and flatten the cheek area), aids in whistling, smiling, and sucking in neonates.
