Which part is located in the anterior region of the corpus callosum?

• A. Splenium
• B. Genu
• C. Body
• D. Rostrum

Answer: (B)

The anterior region of the corpus callosum is the part that forms the front bend connecting the two hemispheres. From front to back, the main segments are rostrum (the very tip), genu (the bend just behind the rostrum), then the body, and finally the splenium at the back. The genu sits at the front portion and mainly links the frontal lobes across sides, which is why it’s identified with the anterior region. The other segments lie more medially or posteriorly: the body connects motor and sensory areas, the splenium connects posterior cortical areas, and the rostrum is the most anterior projection.
