Ans. is 'c' i.e., Cerebellum o Cerebellum, through its connection with the red nucleus influences the activity of brainstem reticular formation and thereby gamma motor neuron activity.o Through its connections with the vestibular nucleus and vestibulospinal tract, cerebellum influnences the activity of alpha motor neurons.o Thus, normal cerebellar function is essential for the maintenance of normal muscle tone and posture.o The cerebellum seems to play crucial roles in walking as well as maintaing a standing posture.o Cerebellar vermis plays an important role in maintenance of standing postureo Basal ganglia is also involved in maintaining posture by acting as relay center for extrapyramidal pathways. But its role is not as important.
