Superior cerebellar artery

Superior cerebellar artery (SCA) is a significant artery in the human body that supplies blood to the cerebellum, a part of the brain that plays a vital role in motor control. The SCA is a branch of the basilar artery, which is one of the main arteries supplying the brain.

Anatomy

The superior cerebellar artery typically arises near the termination of the basilar artery. It winds backward around the brainstem to reach the cerebellum, passing above the oculomotor nerve and under the trochlear nerve. It then divides into rostral and caudal branches to supply different parts of the cerebellum.

Clinical significance

The superior cerebellar artery is susceptible to ischemia, which can lead to cerebellar infarction. Symptoms of a superior cerebellar artery stroke can include ataxia, dysarthria, and nystagmus.
