Close-up view of tributaries of internal cerebral vein
The left half of the fornix has been partly removed. The cut ends of the remaining parts are visible at 11 and 22. The inferior sagittal sinus lies within the falx (20) near its free margin.

- Insula
- Emerging fibers of internal capsule (cut across)
- Posterior parietal branch of middle cerebral artery (cut off)
- Choroid plexus lying within inferior horn of lateral ventricle
- Choroidal glomus (retracted upward)
- Hippocampus
- Collateral trigone
- Branch posterior cerebral artery
- Medullary substance of occipital lobe
- Fornix (column) (cut across)
- Interventricular foramen (of Monro)
- Anterior tubercle of thalamus
- Terminal vein
- Stria terminalis (note that this passes over the vena terminalis)
- Corpus callosum (trunk) (cut through in midline)
- Lamina affixa
- Superior surface of thalamus
- Internal cerebral vein (left)
- Falx cerebri
- Choroidal branch of internal cerebral vein
- Fornix (crus) (cut across)
