The posterior end of the corpus callosum is the thickest part and is termed the splenium (Greek splenion = a bandage). It overlaps the tela chorioidea of the third ventricle and the mid-brain and ends in a thick convex free border. A sagittal section of the splenium shows that the posterior end of the corpus callosum is acutely bent forward the upper and lower parts being applied to each other.
