The topic is the Nervous System are form by neuron ,the dendrive is the nerve tha carries the massenges toward the cell body and axon are the nerve that carries the massenge away from the cell body .Your brain an your spinal cord are your central nervous system.All other nerves are your outher ,or peripheral nrevous system . Like telephone wires your nerve cell join together in "cables",caled nerve. Your brain is surrounded by youe bhard skull bones.It and your spinal cord are protec by specialfluid thet acts like a cishion against socks.We have 5 senses the seeing,tasting,touching,smelling and hearing.
