The corpus callosum definition says that it is a primary region of our brain having a rich and healthy blood supply saving it from infarcts. The callosum mostly receives its supply from the pericallosal artery’s callosal branches which border the callosum’s outer perimeter along with the cingulate sulcus or the callosal sulcus and the subcallosal area. It also receives blood from the anterior communicating artery from either the subcallosal artery or the median callosal. The Genu and rostrum corpus callosum parts and the hypothalamus areas receive the supply from the subcallosal artery. The subcallosal artery and the median callosal artery are similar to each other but the median callosal artery travels further into the corpus callosum body to provide blood supply.
