Question

the corpora quadrigemina is composed of the
cerebral and cerebellar peduncles.
parietal and temporal lobes.
fourth cranial nerve.
superior and inferior colliculi.
first four cranial nerves.

Explanation:

The corpora quadrigemina is a part of the mid - brain. It consists of two superior colliculi (involved in visual reflexes) and two inferior colliculi (involved in auditory reflexes).

• Cerebral and cerebellar peduncles are fiber tracts, not part of corpora quadrigemina.
• Parietal and temporal lobes are parts of the cerebral cortex.
• The fourth cranial nerve (trochlear nerve) is a single nerve, not related to corpora quadrigemina.
• The first four cranial nerves (olfactory, optic, oculomotor, trochlear) are individual nerves, not the composition of corpora quadrigemina.

Answer:

superior and inferior colliculi.
