  1. The posterior part of cerebrum

  2. The anterior part of cerebrum

  3. The part of mesencephalon

  4. None of the above

Show answer
Correct Option: C
Explanation:

The mesencephalon is also called the midbrain. It is a small and reduced part of the brain which connects the forebrain with the brainstem. Its anterior part consists of two longitudinal myelinated nerve fibres called the cerebral peduncles or crus cerebrum or the crura cerebri. The posterior part is made of four colliculi that are called the corpora quadrigemina.

Hence, the correct answer is 'The part of mesencephalon'
