Detailed explanation-1: -The corpus callosum is the largest white matter structure in the brain, consisting of 200–250 million contralateral axonal projections and the major commissural pathway connecting the hemispheres of the human brain.

Detailed explanation-2: -The corpus callosum is part of the white matter of the brain, which is made up of myelinated axons that are extensions of the neuronal cell bodies. It is one of the largest white matter structures in the nervous system, containing over 200 million axons.

Detailed explanation-3: -The corpus callosum has four main parts – individual nerve tracts that connect different parts of the hemispheres. These are the rostrum, the genu, the trunk or body, and the splenium. A narrowed part between the trunk and the splenium is known as the isthmus.

Detailed explanation-4: -The corpus callosum is a white matter tract located in the midline. It arches over the lateral ventricles and connects white matter of the left and right cerebral hemispheres.

Detailed explanation-5: -It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.
