Synonym: Cisterna prepontina
English: , prepontine cistern
Definition[Bearbeiten]
The cisterna pontis is an unpaired cerebrospinal fluid cistern located ventral to the pons and dorsal to the clivus.
Anatomy[Bearbeiten]
The cisterna pontis is separated from the neighbouring cisterns by various arachnoid membranes:
- superiorly by the Liliequist membrane from the cisterna interpeduncularis
- inferiorly by the membrana pontomedullaris medialis from the cisterna premedullaris
- laterally through the anterior pontine membrane from the pontocerebellar cistern
The basilar artery and some of its branches as well as the transverse pontine veins run through the cistern.
