What does it mean when the plasma membrane of the neuron is polarized? - Answer - When there is a separation of charge across the membrane. Specifically, a polarized neuron is one where the inside is more negative and the outside is more positive. This is the state when the neuron is at rest. What gives rise to the gradient across the membrane? - Answer - The chemical and voltage gradients of potassium and sodium. Potassium wants to move from inside to outside. Sodium wants to move from out...

Action potential = ____________ - Answer - Nerve impulse Action potential - Answer - Is unidirectional in that information is always receive down the dendrites and transferred to another cell through the axon terminal Action potential stages - Answer - ng potential arization arization ng potential Resting potential (-70 mv) - Answer - -State or neuron is and when not transmitting a signal -A resting neuron is polarized Depolarization ( voltage charges from -60 mv to a +...
