Medial longitudinal fissure

The longitudinal cerebral fissure (Eng. " longitudinal column of the cerebrum ") is the column ( fissure ), which divides the cerebrum ( telencephalon ) into its two halves ( hemispheres ). It extends on the upper surface of the brain the center of the front to the rear ( the sagittal plane ), and extends in the depth down to the bar ( the corpus callosum ), which consists of the nerve fibers that connect the two hemispheres. The upper edge of the fissure is formed by the circumferential edge, which constitutes the transition from the convex outer surface of the brain to the inner planar surface. In the longitudinal cerebral fissure a protrusion of the dura mater ( dura mater encephali ), the falx cerebri, which gives mechanical support to the brain runs. In it there is also a along the lateral edge extending venous outflow, the superior sagittal sinus.
