Maxillary artery

Maxillary artery is a branch of the external carotid artery that distributes to the deep structures of the face (internal maxillary) and to the side of the face and nose (external maxillary). It is comprised of three portions: the mandibular (bony) portion, the pterygoid (muscular) portion, and the pterygopalatine portion. The mandibular portion is in between the neck of the mandible and the sphenomandibular ligament. The pterygoid portion is in between the two heads of origin of the lateral pterygoid muscle. The pterygomaxillary portion, which is the terminal branch of the maxillary artery, lies in the pterygopalatine fossa.
