Vedclass · Answer

(A) The brain stem is formed by the midbrain,pons,and medulla oblongata. The cerebellum is part of the hindbrain but is not included in the brain stem. Thus,the Assertion is correct.The cerebellum has a highly convoluted surface (folia) to accommodate a large number of neurons,which is essential for its function in coordinating muscular activity and maintaining balance. Thus,the Reason is also correct.However,the Reason does not explain why the brain stem excludes the cerebellum. Therefore,both statements are correct,but the Reason is not the correct explanation for the Assertion.

Assertion : Midbrain and hindbrain (except cerebellum) form the brain stem.
Reason : Cerebellum has very convoluted surface in order to provide the additional space for many more neurons.
