Anatomical terms of neuroanatomy[edit on Wikidata]

The prepontine cistern, or pontine cistern is one of the subarachnoid cisterns situated ventral to the pons. It contains the basilar artery. Each lateral aperture opens into the pontine cistern just posterior to the cranial nerve VIII.

Anatomy

The pontine cistern is situated ventral to the pons, in the interval between ventral aspect of the pons, and the clivus.

Contents

The cistern contains the origin of the abducens nerve (CN VI), the basilar artery and the origin of the basilar artery and of its branches, and the anterior inferior cerebellar artery, and superior cerebellar artery.

Relations

It is continuous inferiorly with the subarachnoid space of the spinal canal, posterolaterally with the cerebellopontine cistern of either side, and rostrally/anteriorly with the interpeduncular cistern.
