Detailed explanation-1: -A fissure is a deeper grove and is often used interchangeably with sulcus . The cerebrum is divided into a left and right hemisphere by a longitudinal fissure that goes by many different names: longitudinal fissure, cerebral fissure, median longitudinal fissure, interhemispheric fissure.
Detailed explanation-2: -The part of the brain that is a deep groove dividing the cerebrum and the cerebellum is called the transverse fissure.
Detailed explanation-3: -The Longitudinal Fissure is the deepest and largest of cortical fissures. It forms the boundary between the cerebral hemispheres. From a coronal view through the cerebral hemispheres, the longitudinal fissure can be seen dipping down to the main fiber tract that connects the hemispheres, the corpus callosum.
