CEREBELLAR ARTERY Meaning and
Definition
-
The cerebellar artery is a term used in anatomy and neurology to refer to the major blood vessels that supply the cerebellum with oxygenated blood. The cerebellum is a vital part of the brain that is responsible for coordinating voluntary movements, balance, posture, and muscle tone. As such, it requires a constant and ample supply of oxygen and nutrients from the blood.
There are three main cerebellar arteries: the superior cerebellar artery, anterior inferior cerebellar artery, and posterior inferior cerebellar artery. These arteries arise from the basilar artery, which is a major branch of the vertebral artery in the brainstem.
The superior cerebellar artery is the largest and supplies the superior and anterior portions of the cerebellum. It runs along the upper surface of the cerebellum, giving off smaller branches that penetrate deep into the tissue. The anterior inferior cerebellar artery supplies the anterior and inferior portions of the cerebellum as well as the internal auditory meatus, which is an opening in the skull that houses the inner ear structures. Lastly, the posterior inferior cerebellar artery provides blood to the posterior portion of the cerebellum, as well as other nearby structures such as the medulla oblongata.
Damage or blockage to any of these cerebellar arteries can have serious consequences for the cerebellum, leading to symptoms such as loss of coordination, balance issues, muscle weakness, and even stroke.
