Question

Quizplus · Accepted Answer

Maintaining muscle tone and balance relies heavily on sensory information from the vestibular system and motor coordination from the cerebellum. Dysfunction in these areas can result in problems with muscle tone and balance. The reticular formation primarily controls arousal and sleep-wake cycles, while the red nucleus is involved in motor coordination of the upper limbs. The cochlear nucleus and inferior colliculi are more involved in auditory processing.
