Anterior inferior cerebellar artery
Anterior Inferior Cerebellar Artery
The Anterior Inferior Cerebellar Artery (AICA) (pronunciation: an-TEER-ee-or in-FEE-ree-or ser-uh-BELL-er AR-ter-ee) is one of the three main arteries that supply blood to the cerebellum. The term originates from the Latin words 'anterior' meaning 'front', 'inferior' meaning 'lower', 'cerebellum' meaning 'little brain', and 'artery' meaning 'air holder'.
Anatomy
The AICA arises from the basilar artery, near the junction of the pons and medulla oblongata. It winds backward around the abducens nerve and enters the cerebellopontine angle, where it often gives rise to the internal auditory (labyrinthine) artery.
Function
The AICA supplies blood to the anterior part of the cerebellum and the lateral pons. It is responsible for carrying oxygenated blood from the heart to these parts of the brain.
Clinical Significance
Blockage or damage to the AICA can result in Anterior Inferior Cerebellar Artery Syndrome (AICAS), also known as Lateral Pontine Syndrome. This condition can cause a variety of symptoms including vertigo, nausea, and hearing loss.
