Cerebellar artery

The Cerebellar artery (pronunciation: /sɛrɪˈbɛlər ˈɑːrtəri/) is a term used to refer to any of the three arteries that supply blood to the cerebellum, a part of the brain responsible for motor control, balance, and coordination. These arteries include the Superior cerebellar artery, Anterior inferior cerebellar artery, and Posterior inferior cerebellar artery.

Etymology

The term "Cerebellar artery" is derived from the Latin words 'cerebellum' meaning 'little brain' and 'arteria' meaning 'windpipe, artery'.

Superior cerebellar artery

The Superior cerebellar artery (SCA) is one of the three main arteries that supply blood to the cerebellum. It arises near the termination of the basilar artery, a major blood vessel of the brain.

Anterior inferior cerebellar artery

The Anterior inferior cerebellar artery (AICA) is another artery that supplies blood to the cerebellum. It arises from the basilar artery and supplies the anterior part of the cerebellum and the inner ear.

Posterior inferior cerebellar artery

The Posterior inferior cerebellar artery (PICA) is the largest of the three cerebellar arteries. It arises from the vertebral artery and supplies the posterior part of the cerebellum and the lower part of the brainstem.

Related terms
