Question 1.The change of potential due to electrotonic spread will get larger the further away from the starting point it travels. True False 2.In which type of potential do voltage-gated channels play a role? A. Electrotonic (Local) potentials B. Action potentials 3.According to this video, what event occurs if the electrotonic spread causes a change of potential from -70mV (at rest) to -55mv? A. Voltage-gated potassium channels open. B.Voltage-gated sodium channels open. 4.The axon hillock is the location of large quantity of voltage-gated channels. True False 5. An action potential helps to “boost” electrotonic potential so that it can spread further (like down an axon) without losing strength.
