The stage in an action potential that immediately follows depolarization is?
The stage that immediately follows depolarization in an action potential is repolarization. During this stage, potassium channels open and potassium ions move out of the cell, leading to a restoration of the cell's negative charge.
What is the stage in an action potential that immediately follow depolarisation?
The stage that immediately follows depolarization in an action potential is repolarization. During repolarization, potassium ions move out of the cell, causing the membrane potential to return to its resting state.
What does psychologist mean when they say that the action potential follows an all or none law?
When psychologists say that the action potential follows an all-or-none law, they mean that once a neuron's membrane reaches a certain threshold of depolarization, it will fire an action potential at full strength. This means that the action potential either occurs completely or not at all; there is no partial firing. The intensity of the stimulus affects the frequency of action potentials but not their strength. Essentially, it underscores the binary nature of neural signaling.
Immediately after a action potential has peaked which cell gate opens?
The potassium (K+) channel gate opens immediately after an action potential has peaked. This allows potassium ions to flow out of the cell, resulting in repolarization of the membrane potential back to its resting state.
Corresponds to the period of repolarization of the neuron?
The period of repolarization of a neuron corresponds to the time when potassium ions move out of the neuron, allowing the cell to return to its resting potential. This phase follows the peak of the action potential when sodium channels close and potassium channels open, leading to membrane potential restoration. Repolarization is essential for the neuron to be able to generate subsequent action potentials.

The resolution of the plot immediately follows the?
falling action
Which stage immediately follows rising action?
climax
According to freytag What stage of plot immediately follows climax?
Rising action and falling action
What does psychologist mean when they say that the action potential follows an all or none law?

The intensity of the stimulus affects the frequency of action potentials but not their strength. Essentially, it underscores the binary nature of neural signaling.
What happens to the neuron after an action potential is fired?
After an action potential is fired, the neuron goes through a refractory period where it cannot fire another action potential immediately. During this time, the neuron resets its electrical charge and prepares for the next signal.
What stage of plot follows the falling action?
The 'falling action' occurs immediately after the climax leading to the resolution or denouement.
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.
Where is the hillock of the neuron?
The nerve cell hillock is the beginning of the axon immediately after the soma. This is where the action potential originates.
How do nerve impulses follow th all-or-nothing principle?
The action action potential produced needs to reach the threshold for the AP to be propagated. If it doesn't reach the threshold, there is not enough Na+ to stimulate the positive feedback system which allows the action potential to be self-propagated. Instead, K+ channels will be opened, and it will enter repolarisation phase, and the AP wll not be conducted. AND ALL YOU PEOPLE OUT THERE MAKE A RUNESCAPE ACCOUNT ! #1 MMO!!!!!!!!!!!!!!!!!! AND DONT DO PRIVATE SERVERS THEY SUCK
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.
