Cerebral longitudinal fissure
The longitudinal cerebral fissure (dt. "Longitudinal gaps of the brain"), and the longitudinal groove or interhemispheric fissure , the column ( fissure ) that the cerebrum ( telencephalon ) into its two halves ( hemispheres , divides). It runs centrally on the top of the brain from front to back ( sagittal ) and extends in depth down to the bar ( corpus callosum ), which consists of the nerve fibers that connect both hemispheres. The upper edge of the fissura is formed by the mantle edge , which represents the transition from the convex outer surface of the brain to the inner flat surface. In the fissura longitudinalis cerebri there is a protrusion of the hard meninges ( dura mater encephali ), the falx cerebri , which gives the brain mechanical support. It also contains a venous outflow, the superior sagittal sinus, running along the edge of the mantle .
