The corpus callosum anatomy is divided into four regions from the front to the rear end. These parts are the splenium, body, genu, and rostrum. All these regions are responsible for being connected to different specific parts of our brain cortex. Corpus callosum MRI has revealed that its structure is a little complicated. In this part of the brain, there is a small narrow area between the splenium and the body in the rear end known as the isthmus. Then the genu fibres crisscross to form the forceps minor that connects the different regions of the frontal brain cortices. Again, the splenium fibres move to the rear side, forming the forceps major, connecting it with the occipital lobes. These fibres make up the corona radiata and other important white matter paths while moving through our brain’s cerebral cortex. Lastly, the rostral fibres connect the orbital region in our frontal lobe.
