The following pertains to our present subject: The nervous centers of man's nervous system, if classified as to function, may be divided into inferior and superior. The inferior centers are characterized by reflex and automatic activities. A stimulus excites the peripheral nerve-endings of some sense-organ. At once a nerve-current is set up in the afferent nerves. The current in its turn stimulates a plexus of central ganglia, the nerve energy of which is set free, and is propagated along the efferent nerves towards muscles and glands,--secretions, muscular contractions and relaxations are the result; biologically regarded, various reactions and adjustments follow"--Book.
