The nervous system his/her function and the production and liberation of electric pulses, his/her main constintuinte are the neurons. the division of the neuron is dentritos = receiver of electric pulses, cellular body = generator of answers to the incentives, axônio = transmitter of the pulses, hems schawn = it controls of the pulses, melina hem = insulator of the neuron and ranvier nodule = am pliador of incentives. division of the nervous system; central nervous system (s.n.c.) that and encephalon costituido and spinal marrow and outlying nervous system (s.n.p.) that and constituted of sensorial nerves (cranial), motor nerves (raquianos) the central nervous system and divided in encephalon = larger portion of the nervous system, procénfalo that is subdivided in telencéfalo (brain) and diencéfalo (cerebellum), mesencefalo, rombencéfalo subdvide-if in metencéfalo (varólio bridge) and mielencéfalo (bulb raquiano), brain = it controls, regulation and coordination of the electric pulses, cerebellum = it controls and balance, bridge = transmitter of electric pulses of the cxerebro the marrow, and the bulb = it controls of the heart and breathing frequency. the outlying nervous system and complement of s.n.c. he/she has connection with the spinal marrow, because it presents great diversity of nerves he works in the marrow in the intention of ordering incentives for cranial nerves (sensitive and mixed) for acting with incentives the system outlying nsevoso it presents a subdivision that and s.n.a (autonomous nervous system) nice and parassinpatico, the nice = constant incentives (it whips) former: dilation pupilar, palpitation and parassinpatico = it generates control of former incentives: concentration pupilar and bracardiaca
