- - - - Consist of Brain, spine and nerves
        
        the tissue and organs are made of cells taht carry information, through the system, called nerve cells or neurons
        
        Neurons
        
        Divide in three types
        
        motor neuron
        
        messages the muscles or gland and reacts accordingly
        
        Inerneuron
        
        moves the message from one neuron to other
        
        sensory neuron
        
        picks stimulus and converts them into a mesage
        
        Nerve Impulses
        
        transports information
        
        the information moves from the dentrite to the axon, by the energgy impulses.
        
        Synapse
        
        the process in which the inpulse transfers
        
        the energy/ impulse/ electrical signal travels through the neurons
  - - - Composed by Nerves
    - - Made up of the brain and the spine
