1. A Describe all the events of impulse transmission including the graded potential, the action potential and its transmission from one neuron to the next. Give as much detail as possible. 1.B Give two interesting medical implications, applications or facts about  neurotransmitters.    (Answer both questions. But concentrate on the first one which is worth most of the points.)
