What else can I help you with?
Define the period of repolarization when only a strong stimulus will elicit an action potential?
The period of relative refractory period is the time after an action potential during which a strong stimulus is required to generate a new action potential. This is because the membrane potential is hyperpolarized, making it more difficult to reach the threshold for firing another 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.
What transmission of the depolarization wave along the neurons membrane?
Action potential
During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
Why does the action potential travel in one direction?
The action potential travels in one direction because of the refractory period, which prevents the neuron from firing again immediately after an action potential has been generated. This ensures that the signal moves in a linear fashion along the neuron.

What was the effect of curare on eliciting an action potential?
It creates an action potential
How did increasing the stimulus voltage in the simulation affect the action potential?
Increasing the stimulus voltage in the simulation affect action potential mainly because increasing the current will automatically increase the voltage.
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 an action potential propagate unidirectionally along an axon?
An action potential propagates unidirectionally along an axon because of the refractory period, which prevents the neuron from firing in the opposite direction immediately after an action potential is generated. This ensures that the signal travels in one direction, from the cell body to the axon terminal.
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.
Also called a nerve impulse transmitted by axons?
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
Why do action potentials propagate in one direction?
Action potentials propagate in one direction because of the refractory period, which is a brief period of time after an action potential where the neuron is unable to generate another action potential. This ensures that the signal travels in a linear fashion along the neuron and does not backtrack.
