What is the labyrinthine artery?
The labyrinthine artery, also known as the auditory artery or internal auditory artery, is a long and slender artery that is the main arterial supply to the vestibular apparatus and cochlea. It also vascularizes the VII and VIII cranial nerves.
Is labyrinthine artery an end artery?
The labyrinthine artery is an end artery, thus does not communicate with any other vessel in the temporal bone. Because of the inner ear’s singular blood supply, both the vestibular and auditory structures are especially vulnerable to ischemic events.
Where is labyrinthine artery?
In about one-third of patients, one labyrinthine artery originates outside of the internal acoustic meatus and is found on the cochlear nerve below the facial nerve ending in the fundus of the internal acoustic meatus between the cochlear and vestibular nerves.
What does the AICA supply?
Introduction. The anterior inferior cerebellar artery (AICA) is one of the lateral branches of the basilar artery which supplies various structures of the posterior cranial fossa, most importantly the cerebellum and pons.
Do you have arteries in your ears?
The posterior auricular artery is a smaller muscular artery that branches from the external carotid artery. This artery travels to the region posterior to the ear. The function of the posterior auricular artery is to perfuse the scalp and the ear.
How can I improve the circulation in my ear?

- Meditation.
What increases blood flow to the ears?
Magnesium is known to help expand the blood vessels and extend circulation (even all the way in your inner ear). In addition to increasing blood flow, it also controls the release of glutamate.
Where is AICA?
The anterior inferior cerebellar artery (AICA) is one of three pairs of arteries that supplies blood to the cerebellum. It arises from the basilar artery on each side at the level of the junction between the medulla oblongata and the pons in the brainstem.
What is a pica stroke?
The Posterior Inferior Cerebellar Artery (PICA) carries blood to this part of the brain. This stroke (Wallenberg’s Syndrome) causes the person to have balance problems and lean to one side. They may also have numbness on one side of the face and body and an eye droop. They may have hoarseness and trouble swallowing.
What causes narrowing of the arteries in the brain?
Intracranial stenosis, also known as intracranial artery stenosis, is the narrowing of an artery in the brain, which can lead to a stroke. The narrowing is caused by a buildup and hardening of fatty deposits called plaque. This process is known as atherosclerosis.
