Splenium

Brain: Splenium
Median sagittal section of brain. The relations of the pia mater are indicated by the red color. (The corpus callosum is the gray curved figure in the center, and the splenium is labeled at upper right.)

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.
