Solution The human nervous system is like the telephone network, cause it do the same thing , all the impulses that a human has respond through all the nerves which are connected to the base of the brain, and all signals and messages go to the brain, and the mind respond by sending an impulse to the given area ,and an action is preformed,then impulses are send back,for new impulses to be send by the brain, so that is why it is like a telephone system. The Human brain acts as the CENTRAL PROCESSING UNIT, where each of the actions performed by the other parts of the body are analyzed and the tasks are assigned to various parts of the brain- namely cerebrum and cerebellum.
