Exploration of the brain from the medial aspect
Lateral ventricle; internal cerebral vein within transverse fissure
The septum pellucidum has been cut away to expose the lateral ventricle. The column of the fornix (3) has been cut opposite the foramen of Monro and the body of the fornix turned upward. A thickened part of the septum pellucidum (also cut) is associated with the fornix. This is continuous with tissue in the subcallosal gyrus. The choroid plexus of the third and lateral ventricles bounds the most anterior extent of the transverse fissure. The internal cerebral vein (5) is injected and most of the visible branches lie within the transverse fissure.
- Inferior surface of fornix (fornix reflected upward)
- Caudate nucleus (forming sloping floor of anterior horn of lateral ventricle)
- Fornix column (divided)
- Thickened part of septum pellucidum continuous into subcallosal gyrus
- Internal cerebral vein
- Stria terminalis
- Choroid plexus continuing through interventricular foramen from roof of third ventricle to body of lateral ventricle
- Position of interventricular foramen (of Monro)
- Subcallosal gyrus
- Anterior commissure (cut across)
- Fornix (column) approaching mammillary body
