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:
Brain stem consists of: Midbrain, Pons, and Medulla oblongata! Cerebrum is part of the FOREBRAIN, not brain stem! Statement II is incorrect; Statement I is correct!
A deep cleft divides the cerebrum longitudinally into two halves, which are termed as the left and right cerebral hemispheres. The hemispheres are connected by a tract of nerve fibres called corpus callosum. Thus, Statement I is correct.
NCERT states explicitly: "Three major regions make up the brain stem; mid brain, pons and medulla oblongata. Brain stem forms the connections between the brain and spinal cord." Statement II falsely includes the cerebrum (forebrain) while omitting the midbrain. Thus, Statement II is incorrect.
Statement I is correct but Statement II is incorrect, matching Option (1).
Diagnose every choice: Know exactly why the right option works and why distractors fail.
Statement I correctly defines corpus callosum; Statement II incorrectly includes the cerebrum in the brainstem.
Statement I is correct and Statement II is incorrect.
Statement II is incorrect because cerebrum is not a brainstem component.
Statement I is factually correct.
Confusing the midbrain with the cerebrum when reciting brain stem components.
"The hemispheres are connected by a tract of nerve fibres called corpus callosum... Three major regions make up the brain stem; mid brain, pons and medulla oblongata. Brain stem forms the connections between the brain and spinal cord."
