alveolaris inferior; inferior dental artery) descends with the inferior alveolar nerve to the mandibular foramen on the medial surface of the ramus of the mandible.
Crossing the under surface of the sphenoid the sphenopalatine artery ends on the nasal septum as the posterior septal branches; these anastomose with the ethmoidal arteries and the septal branch of the superior labial; one branch descends in a groove on the vomer to the incisive canal and anastomoses with the descending palatine artery.

 CHAPTER 48: THE PAROTID, TEMPORAL AND INFRATEMPORAL REGIONS
The superficial temporal artery, the smaller terminal branch of the external carotid artery, arises in the parotid gland, posterior to the neck of the mandible.
The maxillary artery, the larger terminal branch of the external carotid artery, arises in the parotid gland, posterior to the neck of the mandible.
The chief branches are several superior alveolar arteries, the infra-orbital and descending palatine arteries, the artery of the pterygoid canal, and the sphenopalatine artery.

  External carotid artery - Wikipedia, the free encyclopedia
The external carotid artery begins opposite the upper border of the thyroid cartilage, and, taking a slightly curved course, passes upward and forward, and then inclines backward to the space behind the neck of the mandible, where it divides into the superficial temporal and maxillary arteries after passing through the parotid gland.
Medial to it are the hyoid bone, the wall of the pharynx, the superior laryngeal nerve, and a portion of the parotid gland.
Posterior to it, near its origin, is the superior laryngeal nerve; and higher up, it is separated from the internal carotid by the Styloglossus and Stylopharyngeus, the glossopharyngeal nerve, the pharyngeal branch of the vagus, and part of the parotid gland.

 Maxillary artery - Wikipedia, the free encyclopedia
The maxillary artery (or internal maxillary artery in older texts) is an artery that supplies deep structures of the face.
It supplies the deep structures of the face, and may be divided into mandibular, pterygoid, and pterygopalatine portions.
Formerly, the term "external maxillary artery" was used to describe what is now known as the facial artery (per Terminologia anatomica.) Currently, the term "external maxillary artery" is less commonly used, and the terms "internal maxillary artery" and "maxillary artery" are equivalent.

The artery ends by passing into the pterygopalatine fossa, where it gives off its terminal branches whose final destinations are: the nasal cavity (sphenopalatine branch), maxilla and maxillary teeth (infraorbital and posterior superior alveolar branches) and pharynx (pharyngeal branches and artery of the pterygoid canal).

 ANNALS Feb1998: ENDOSCOPIC LIGATION OF THE INTERNAL MAXILLARY ARTERY FOR TREATMENT OF INTRACTABLE . . .   (Site not responding. Last check: 2007-10-20)
The internal maxillary artery divides into terminal branches within the pterygomaxillary fossa, sending branches through the bony maxilla to exit the posterolateral nasal wall in the posterior aspect of the middle meatus.
Endoscopic identification and ligation of these terminal branches of the internal maxillary artery (the sphenopalatine and nasopalatine arteries) as they exit the maxilla has been performed on 10 patients with a 100% success rate and no morbidity or mortality associated with the procedure.
The ascending scale of treatment previously outlined in the literature may be amended, as a potentially definitive procedure is available, and we believe that this technique is easier to perform, has less associated morbidity, and has equal efficacy in comparison to transantral ligation or percutaneous embolization in the treatment of intractable posterior epistaxis.
