a) Diagram the transmission of information in the human body during a reflex response to a harmful stimulus such as touching a hot dish. Label your diagram to identify structures carrying the information, the direction of impulse, and the starting and ending structures involved in the pathway. (6 points)

b) Diagram a neuron in the midst of conducting a nerve impulse. Your diagram should show changes in ion movement, and changes in internal and external net charge (+ or -) as the impulse is propagated. (6 points)

c) Diagram the connection between neurons to show how a nerve impulse travels from one neuron to another. Your diagram should show the direction of impulse and key structures involved in the transmission of the impulse. Label all structures. (6 points)
