                     The  nervous  system  regulates
                     and  directs  all  the  functions
                    of  our  body.  The  brain  is  the
                    center  of  the  nervous  system,
                     it  is  used  to  think  and,  helped
                       by  the  nerves,  receives
                      messages  and  sends  orders.



















                                                  The  nervous  system  is  made  up  of:
                                                  a)  the  brain
                                                  b)  spinal  cord
                                                  c)  nerves









                 The  neuron  is  the  cell  that
                 receives,  conducts  and  transmits
                 nerve  impulses.
