Answer 1

The role of the Corpus Callosum is to connect the right and left lobes of the cerebral hemispheres.

Question 2

What type of brain matter is the corpus callosum (grey vs white).

Answer 2

White matter - specifically commissural fibres.

Question 3

Of the three types of white matter fibres in the brain (projection, commissural and association fibres) which is the Corpus Callosum?

Answer 3

Commissural fibres.

Question 4

The corpus callosum has two main bundles of fibres located at the posterior and anterior ends. What are these called?

Answer 4

Posterior end: Forceps major
Anterior end: Forceps minor

Question 5

The corpus callosum when viewed in the sagittal plane has four sections.
What are these called?

Answer 5

1. Splenium (connects occipital and posterior temporal lobes)
2. Body (connects parietal and posterior frontal lobes)
3. Geniu (connects prefrontal lobes)
4. Rostrum (connects orbitofrontal lobes

2. Body
3 Geniu
4. Rostrum

Answer 6

1. Splenium (connects occipital and posterior temporal lobes)
2. Body (connects parietal and posterior frontal lobes)
