Anterior inferior cerebellar artery segments

The length of the anterior inferior cerebellar artery can be divided into four segments including the anterior pontine (close to the abducens nerve), lateral pontine (close to the facial and vestibulocochlear nerves), floccu peduncular, and cortical segments. The lateral pontine segments can be further divided into pre-meatal, meatal, and postmeatal segments. The segments are named because of their relationship with the internal auditory meatus ¹⁾.
