What is the function of the anterior inferior cerebellar artery?
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.
What happens if the anterior inferior cerebellar artery is damaged?
Syndrome of Anterior Inferior Cerebellar Artery Occlusion Usual symptoms are nausea, vertigo, tinnitus, and hearing loss. Other features include vomiting, ipsilateral facial numbness, facial palsy, Horner syndrome, and contralateral loss of pain and temperature.
Does the anterior inferior cerebellar artery supply the medulla?
Artery in the brain that supplies part of the cerebellum. The AICA lies near the surface of a vestibular schwannoma. It arises from the lower part of the basilar artery at the level of the junction between the medulla oblongata and the pons in the brainstem.
Where is the anterior inferior cerebellar artery?
cerebellum
The anterior inferior cerebellar artery is located in the cerebellum of the brain. The cerebellum is just above the brainstem and controls coordination of movement and balance, among other important functions. The anterior inferior cerebellar artery originates at the basilar artery of the brainstem.
What does the anterior cerebral artery supply?
To summarize, the ACA supplies the medial and superior parts of the frontal lobe, and the anterior parietal lobe.
Which cranial nerve is adjacent to the anterior inferior cerebellar artery?
The anterior inferior cerebellar artery (AICA) is a branch of the basilar artery. AICA travels across the pons to the cerebellopontine angle, where it lies adjacent to cranial nerves VII and VIII, proceeds to the internal auditory meatus, and travels along the surface of the cerebellum.
What is anterior inferior cerebellar artery infarction?
Conclusions—Infarction in the anterior inferior cerebellar artery territory can present with a broad spectrum of audiovestibular dysfunctions. Unlike a viral cause, labyrinthine dysfunction of a vascular cause usually leads to combined loss of both auditory and vestibular functions. (Stroke.
What does the posterior inferior cerebellar artery supply?
The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain.
What artery supplies Broca’s area?
Superior branches of MCA supply these key functional areas: Broca’s area and other related gray and white matter important for language expression–in the language-dominant (usually left) hemisphere.
What do the cerebellar arteries supply?
The anteroinferior cerebellar artery (AICA) supplies the pons, the facial and spinal trigeminal nucleus and tract, as well as the inferior and middle cerebellar peduncles and spinothalamic tract.
What happens if posterior cerebral artery is blocked?
Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery (PCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the …
What does anterior cerebral artery supply?
What artery supplies the anterior lobe of the cerebellum?
The cerebellum receives vascular supply from three main arteries that originate from the vertebrobasilar anterior system: the superior cerebellar artery (SCA), the anterior inferior cerebellar artery (AICA), and the posterior inferior cerebellar artery (PICA).
What is the function of the anterior cerebral artery?
Anterior cerebral arteries supply blood to the frontal lobes’ anterior (front) aspects, areas responsible for higher-level cognition, including judgment and reasoning. Blockages of these arteries can result in cerebral dementia and speech difficulties.
What happens when the anterior cerebral artery is affected?
Bilateral occlusion of Anterior Cerebral Arteries at their stems results in infarction of the anteromedial surface of the cerebral hemispheres: Paraplegia affecting lower extremities and sparing face/hands. Incontinence. Abulic and motor aphasia.
What happens if the anterior cerebral artery is damaged?
