Important nuclei of the indirect (multineural) system that receive impulses from the equilibriumapparatus of the inner ear and to maintain balance by varying muscle tone of posturalmuscles are the
a) red nuclei
b) superior colliculi
c) vestibular nuclei
d) reticular nuclei

C) vestibular nuclei

Explanation:

The vestibular nuclei occupy the vestibular area. They are four in number, lateral, medial, superior and inferior. Each has its own characteristics and connections. The vestibular nuclei receive nerve impulses originating from the vestibular part of the inner ear and informing about the position and movements of the head. These impulses pass through the sensory neurons of the vestibular ganglion and reach the vestibular nuclei through the central extensions of these neurons, which together form the vestibular part of the nerve.

In other words we can state that the vestibular nuclei are responsible for receiving impulses from the equilibrium state of the inner ear and help maintain balance by varying the muscle tone of the postural muscles.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

answer: the answer is b
