Editing Ear (section)

===Blood supply===
The blood supply of the ear differs according to each part of the ear.

The outer ear is supplied by a number of arteries. The [[posterior auricular artery]] provides the majority of the blood supply. The [[anterior auricular branches|anterior auricular arteries]] provide some supply to the outer rim of the ear and scalp behind it. The posterior auricular artery is a direct branch of the external carotid artery, and the anterior auricular arteries are branches from the [[superficial temporal artery]]. The [[occipital artery]] also plays a role.<ref name=GRAYS40TH_37 />

The middle ear is supplied by the mastoid branch of either the [[occipital artery|occipital]] or [[posterior auricular artery|posterior auricular arteries]] and the [[deep auricular artery]], a branch of the [[maxillary artery]]. Other arteries which are present but play a smaller role include branches of the [[middle meningeal artery]], [[ascending pharyngeal artery]], [[internal carotid artery]], and the artery of the [[pterygoid canal]].<ref name=GRAYS40TH_37 />

The inner ear is supplied by the anterior tympanic branch of the maxillary artery; the stylomastoid branch of the posterior auricular artery; the petrosal branch of middle meningeal artery; and the [[labyrinthine artery]], arising from either the [[anterior inferior cerebellar artery]] or the [[basilar artery]].<ref name="GRAYS40TH_37" />
