Which portion connects the parietal and occipital lobes?

Which portion connects the parietal and occipital lobes?

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

Answer: (C)

The posterior portion of the corpus callosum, known as the splenium, serves as the main bridge linking the back regions of the two hemispheres. Its fibers connect the occipital cortices across sides and, to include posterior parietal areas, enabling cross-hemispheric communication for visual processing and spatial integration. A helpful way to picture this is the forceps major, the bundle of fibers passing through the splenium to connect the occipital lobes. The other parts of the corpus callosum have different primary targets: the front end (genu) connects frontal regions, the middle portion (body) mostly links frontal and parietal areas, and the rostrum sits anteriorly connecting more ventral/frontal regions.
