See: interpeduncular fossa. Synonym: cisterna interpeduncularis, basal cistern, cisterna basalis, cisterna cruralis, Tarin's space. (05 Mar 2000) |

Synonym: ampulla chyli, chyle cistern, chylocyst, Pecquet's cistern, Pecquet's reservoir, receptaculum chyli, receptaculum pecqueti. (05 Mar 2000) |
| cerebellomedullary cistern | The largest of the subarachnoid cisterns between the cerebellum and the medulla oblongata; may be divided into a dorsal cistern located between the cerebellum and dorsal surface of the medulla (cisterna magna) and a lateral cistern located between the cerebellum and the lateral aspect of the medulla. Synonym: cisterna cerebellomedullaris, cisterna magna. (05 Mar 2000) |

| cistern of cytoplasmic reticulum | See: cisterna. (05 Mar 2000) |
| cistern of great cerebral vein | <anatomy, vein> An expansion of the subarachnoid space extending forward between the corpus callosum and the thalamus; it encloses the internal cerebral veins which caudally join to form the vena magna cerebri (Galen's vein). Synonym: ambient cistern, Bichat's canal, Bichat's foramen, cistern of great vein of cerebrum, cisterna ambiens, cisterna superioris, cisterna venae magnae cerebri, superior cistern. (05 Mar 2000) |
| cistern of great vein of cerebrum | <anatomy, vein> An expansion of the subarachnoid space extending forward between the corpus callosum and the thalamus; it encloses the internal cerebral veins which caudally join to form the vena magna cerebri (Galen's vein).
