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.

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
Will a hyperpolarization graded potential lead to an action potential?
No, hyperpolarization graded potentials do not lead to action potentials. Hyperpolarization makes the membrane potential more negative, which inhibits the generation of an action potential by increasing the distance from the threshold potential needed to trigger an action potential.
What is the regeneration of action potential called?
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
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
The start of an action potential?
The action potential begins when the neuron is stimulated and reaches a certain threshold of excitation. This causes voltage-gated ion channels to open, allowing a rapid influx of sodium ions into the neuron, leading to depolarization. This depolarization triggers a cascading effect along the neuron's membrane, resulting in the propagation of the action potential.
Can subthreshold stimulation cause an action potential?
No, subthreshold stimulation is not sufficient to trigger an action potential. The membrane potential needs to reach a certain threshold level for an action potential to be generated. Subthreshold stimulation only produces graded potentials that do not reach the threshold for firing an action potential.
