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.

How is an action potential self-regenerating?
depolarizing currents established by the influx of Na+ flow down the axon and trigger an action potential at the next segment
Why is an action potential is self-regenerating?
The Na+ diffusing into the axon during the first phase of the action potential creates a depolarizing current that brings the next segment, or node, of the axon to threshold.
What is the difference between local potential and action potential?
Local Potentials: Ligand regulated, may be depolarizing or hyperpolarizing, reversible, local, decremental Action Potentials: Voltage regulated, begins with depolarization, irreversible, self-propagating, nondecremental.
The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
What transmission of the depolarization wave along the neurons membrane?
Action potential

How does skin work?
skin works as a self regenerating suit to keep all the innards/fluids in

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
