=THE NERVOUS SYSTEM= BY:NINA + GAELAN

THE NERVOUS SYSTEM IS ONE OFF THE MOST IMPORTANT media type="youtube" key="xRkPNwqm0mM" width="338" height="280" align="right" THINGS IN YOUR BODY. THE NERVOUS SYSTEM PROTECTS YOUR BODY BY SENDING MESSAGES TO YOUR BRAIN. FOR INSTANCE, IF YOU WERE TOUCHING A HOT FRYING PAN YOUR NERVES IN YOUR BODY TELL YOU THAT YOU BURNT BY A FRYING PAN AND THAT YOUR SKIN WILL DIE SOON, AND THAT YOU SHOULD PROBABLY CO AWAY FROM IT. ANOTHER EX...IS WHEN YOUR TOUCH SOMETHING SMOOTH LIKE A FUZZY STUFFY YOU FEEL THE SMOOTHNESS THAT TELLS YOU THAT YOU AREN'T GOING TO GET BURNT LIKE YOU WOULD IF YOU TOUCH A FRYING PAN.

LET'S SAY YOU HAVE A TRAIN STATION AS A PROP. THE MAIN MEETING AREA IS THE BRAIN, THE MAIN TRACK IS THE SPINAL CORD, AND ALL THE BRANCHES BRANCHING OFF OF THE SPINAL CORD ARE THE ARMS IN YOUR BODY AND YOUR LEGS, BUT THE RUNS IN OF YOUR BODY ARE THE GANGLIAS. THE SPECIALIZED media type="youtube" key="i-NgGKSNiNw" width="339" height="280" align="right" CELLS CALLED NEURONS ARE THE TRAINS SENDING THE MESSAGES TO THE MAIN TRACK WITCH IS THE SPINAL CORD WITCH SENDS THE MESSAGE TO THE BRAIN. THE MEETING WILL TELL THE BRAIN TO TELL THE TRAINS THAT THE MESSAGE IS CLEAR AND THAT THE TRAIN CAN PASS AND TAKE ALL THE PASSENGERS TO THERE STOP.

THE NERVOUS SYSTEM, BRAIN, SPINAL CORD, AND NERVES ARE ALL LIVING NETWORKS THAT ARE FORMED IN YOUR BODY. THERE ARE TWO TYPES OF FIBERS IN YOUR BODY, ONE SENDS MESSAGES TO THE BRAIN AND THE OTHER SENDS MESSAGES AWAY FROM THE BRAIN TO SOME PLACE IN YOUR BODY. CELLS THAT MAKE THE NERVOUS SYSTEM ARE CALLED NEURONS. A NORMAL NEURON HAS TWO ANOTHER TYPES OF STRUCTURES LONG FIBERS THAT EXTEND FROM THE BODY OF THE CELL, THESE FIBERS ARE ALMOST ALWAYS WRAPPED UP IN A media type="youtube" key="z6t9Yss45VI" width="339" height="280" align="right" FATTY MATERIAL CALLED MYELIN.

THE OTHER FIBER IS THE FIBER THAT SEND THE MESSAGES OUT OF THE BRAIN TO YOUR BODY ARE CALLED AXONS. A NEURON BODY WILL SOMETIMES CLUSTER UP AND FORM A GANGLIA, WITCH HAS GROUPS OF CELLS THAT ARE READY TO SEND A MESSAGE. EACH CELL WILL ONLY HAVE IT'S RUN, BECAUSE AFTER IT GETS TO GANGLIA IT SENDS THE MESSAGE TO ANTHER CELL WHICH EITHER WILL GIVE THE MESSAGE TO ANOTHER CELL OR IT WILL SEND IT TO THE SPINAL CORD WHICH WILL SEND THE MESSAGE TO THE BR  AIN.
