The sphenopalatine artery is the artery commonly responsible for epistaxis (difficult to control bleeding of the nasal cavity, especially the posterior nasal cavity). [3] In severe nose bleed cases which do not stop after intense packing of anti-clotting agents, the sphenopalatine artery can be ligated (clipped and then cut) during open surgery ...
The maxillary artery, the larger of the two terminal branches of the external carotid artery, arises behind the neck of the mandible, and is at first imbedded in the substance of the parotid gland; it passes forward between the ramus of the mandible and the sphenomandibular ligament, and then runs, either superficial or deep to the lateral pterygoid muscle, to the pterygopalatine fossa.
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.

The facial artery arises in the carotid triangle from the external carotid artery, [1] [2] a little above the lingual artery, and sheltered by the ramus of the mandible.It passes obliquely up beneath the digastric and stylohyoid muscles, over which it arches to enter a groove on the posterior surface of the submandibular gland.
a posterior ethmoidal artery, a branch of the ophthalmic artery, a branch of the internal carotid artery. [1] There is contention as whether this is truly part of Kiesselbach's plexus. Most sources quote that it is not part of the plexus, but rather one of the blood supplies for the nasal septum itself.
The mucous membrane of [citation needed] the frontal sinus receives arterial supply from the supraorbital artery, and anterior ethmoidal artery. [2] Venous drainage is provided by the superior ophthalmic vein. [2] Lymph is drained into the submandibular lymph nodes. [2]
The sphenopalatine artery passes through the sphenopalatine foramen into the cavity of the nose, at the back part of the superior meatus.Here it gives off its posterior lateral nasal branches which spread forward over the conchæ and meatuses, anastomose with the ethmoidal arteries and the nasal branches of the descending palatine, and assist in supplying the frontal, maxillary, ethmoidal, and ...
The anterior ethmoidal artery is a branch of the ophthalmic artery in the orbit. [1] It exits the orbit through the anterior ethmoidal foramen alongside the anterior ethmoidal nerve. It contributes blood supply to the ethmoid sinuses, frontal sinuses, the dura mater, lateral nasal wall, and nasal septum. It issues a meningeal branch, and nasal ...
