Anatomical terms of neuroanatomy

The pontine cistern (or prepontine cistern[1]) is a subarachnoid cistern situated ventrally/anteriorly to the pons.[1][2][3]: 478  It contains the basilar artery.[3]: 478  Each lateral aperture opens into the pontine cistern just posterior to the cranial nerve VIII.[2][3]: 483 

Anatomy

The pontine cistern is situated ventrally/anteriorly to the pons,[1][2] in the interval between ventral aspect of the pons, and the clivus.[3]: 478 

Contents

The cistern contains the origin of the abducens nerve (CN VI),[1][2] the basilar artery[2] and the origin of the basilar artery and of its branches,[1] and the anterior inferior cerebellar artery, and superior cerebellar artery.[1][2]

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.[1]
