Question

The genu and splenium in the brain are associated with
A. Cerebellum
B. Cerebrum
C. Medulla oblongata
D. Vermis

Answer 1

Hint:- Genu and splenium are the anterior and the posterior part of the corpus callosum of the brain respectively. Corpus callosum is a wide thick nerve tract that lies beneath the cerebral cortex.

Complete answer:
As we know from the above hint that genu and splenium are the anterior and posterior part of the Corpus callosum of the brain respectively. It is the largest part of the brain called the white matter .
The corpus callosum has four major parts; individual nerve tracts that connect different parts of the hemispheres. These are the rostrum, the trunk or body, the genus and the splenium.
Fibres from the trunk and the splenium are together known as the tapetum form the roof of each lateral ventricle.
The front part of the corpus callosum, that is towards the frontal lobe is called the genu.
The thinner part of the corpus callosum is the rostrum. The end part or the posterior part towards the cerebellum is called splenium.
The trunk or the body lies between the genu and the splenium.
Additional Information: Corpora straita is the trey matter present in cerebral hemisphere. It is also called paracoel. The genu and the splenium are only found in the brain of mammals. As one matures and the brain develops the corpus callosum plays an important role in motor functions of the body.

Hence, the correct answer is option (B) cerebrum.

Note:- Corpus callosum consists of millions of axons that interconnect two hemispheres. The splenium connects the occipital lobe and temporal lobe. Whereas , the genus connects the frontal lobes for right and left hemispheres.
