How does an action potential differ from a graded potential?
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.
Where do most action potentials originate?
initial segment
Why do not action potentials occur during the repolarization phase?
It has to do with what types of channels are open during this phase. In the repolarization phase the number of potassium channels are increased and the number of sodium channels are decreased. This allows for action potentials to not occur. Otherwise, the action potentials would add up and produce tetany.
A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
Where do action potentials associated with heartbeat regulation originate?
the action potentials associated with heartbeat regulation originate in the SA node, I believe it is in somewhere in the wall of the right atrium of the heart
Do action potentials become weaker with distance?
action potentials are non-decremental and do not get weaker with distance.
What do intercalated discs transfer from cell to cell?
action potentials, ionic currents, the force of contraction and ionic currents and action potentials only

Communication in the nervous system depends on?
action potentials
Does nervous tissue generate action potentials?
Yes.

A nerve impulse consists of a wave of?
Action Potentials

The cells of the retina in which action potentials are generated are the?
ganglion cells
What is the time between the action potentials?
Called an interspike interval
