Question

Given below are two statements:

Statement I: The cerebral hemispheres are connected by nerve tract known as corpus callosum.

Statement II: The brain stem consists of the medulla oblongata, pons and cerebrum.

In the light of the above statements, choose the most appropriate answer from the options given below:

(1) Both Statement I and Statement II are correct. 

(2) Both Statement I and Statement II are incorrect. 

(3) Statement I is correct but Statement II is incorrect.

Answer 1

Correct option is (3) Statement I is correct but Statement II is incorrect.

In human brain, a deep cleft divides the cerebrum longitudinally into two halves, which are termed as the left and right cerebral hemispheres. The cerebral hemispheres are connected by a tract of nerve fibres called corpus callosum.

Three major regions make up the brain stem i.e. mid brain, pons and medulla oblongata.

Cerebrum is a part of forebrain which does not form brain stem.

Options (1), (2) and (4) are incorrect.
