Solution
The correct option is C Superior colliculi
The posterior part of the midbrain, called the tectum, contain 4 rounded elevations.
The 2 superior elevations, nuclei known as the superior colliculi serve as reflex centres for certain visual activities.These are also responsible for the reflexes that govern movement of the head, eyes and trunk in response to visual stimuli.
The 2 inferior elevations, the inferior colliculi, are part of the auditory pathway, relaying impulses from the receptors for hearing in the inner ear to the brain.
Anterior part of the midbrain contains paired bundles of axons known as the cerebral peduncles.
