Nerve Fiber Bundles on the Ventrolateral Surface of the Mesencephalon

Question

Nerve fiber bundles on the ventrolateral surface of the mesencephalon are the
A) tectum.
B) corpora quadrigemina.
C) cerebral peduncles.
D) superior colliculi.
E) inferior colliculi.

Accepted Answer

The cerebral peduncles are nerve fiber bundles located on the ventrolateral surface of the mesencephalon, which is also known as the midbrain. The tectum refers to the dorsal surface of the midbrain, while the corpora quadrigemina are a part of the tectum that includes the superior and inferior colliculi. However, neither the superior nor inferior colliculi are nerve fiber bundles on the ventrolateral surface of the midbrain.
