Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.

Why is action potential self-regenerating?
By self regenerating, they mean that when you start an action potential, it continues in proximal (nearby) tissue (e.g., nerve). The depolarization of the action potential continues along the nerve.

The start of an action potential?
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
What element goes into the cell to start an action potential?
Sodium ions (Na 2+).
What was the effect of curare on eliciting an action potential?
It creates an action potential
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
Why does curare create an action potential?
Curare does NOT create an action potential. It binds to nicotinic acetylcholine receptors (which are primarily excitatory), and prevents the formation of an action potential.
Why does curare appear to generate an action potential?
It doesn't. I prevents an action potential from forming.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Also called a nerve impulse transmitted by axons?
action potential
What is the difference between a compound action potential and a single action potential?
Single action potentials follow the "all or none" rule. That is, if a stimulus is strong enough to depolarize the membrane of the neuron to threshold (~55mV), then an action potential will be fired. Each stimulus that reaches threshold will produce an action potential that is equal in magnitude to every other action potential for the neuron. Compound action potentials do not exhibit this property since they are a bundle of neurons and have different magnitudes of AP's. Thus compound action potentials are graded. That is, the greater the stimulus, the greater the action potential.
