How is an action potential self-regenerating?
An action potential is self-regenerating due to positive feedback mechanisms. When a neuron reaches the threshold potential, voltage-gated sodium channels open, allowing sodium ions to enter the cell and depolarize it. This depolarization triggers neighboring sodium channels to open, propagating the action potential along the neuron.
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.
Would an action potential be possible without the presence of proteins?
No, proteins play a critical role in generating and propagating action potentials in neurons. Channels and pumps made of proteins are responsible for the movement of ions across the cell membrane, which is crucial for the changes in membrane potential that underlie an action potential. Without proteins, the necessary ion movements would not occur, and an action potential would not be possible.
What is the movement of an action potential along an axon?
It can be called a NEURAL IMPULSE, or a NEURAL SIGNAL.It might also be called the FIRING of the neuron.It's usually just referred to as the ACTION POTENTIAL, even though the AP is really just an event at a measured point along the axon, since that local event is self propagating along the axon.And if it were a MYELINATED axon, the propagation would be called SALTATORY CONDUCTION.
Where do neurotransmitters that bind the postsynaptic membrane generate?
Neurotransmitters that bind to the postsynaptic membrane generate a response by either depolarizing or hyperpolarizing the postsynaptic neuron. This response can lead to the generation of an action potential if the threshold is reached, propagating the signal further along the neuron.
How is an action potential self-regenerating?

When a neuron reaches the threshold potential, voltage-gated sodium channels open, allowing sodium ions to enter the cell and depolarize it. This depolarization triggers neighboring sodium channels to open, propagating the action potential along the neuron.
Why is there an overshoot in action potential?
An overshoot in action potential occurs due to the rapid influx of sodium ions causing the membrane potential to become more positive than the resting potential. This depolarization phase is necessary for propagating the action potential along the neuron.
What event most directly triggers the release of calcium from the terminal cisternae?
action potential propagating down the T tubule

How do you use propagating in a sentence?
propagate is used as an action verb. example; He is propagating his ideas in the community.

What is an established church?
An established church is a self governing/autonomous and self propagating church.
Where do neurotransmitters that bind the postsynaptic membrane generate?
Neurotransmitters that bind to the postsynaptic membrane generate a response by either depolarizing or hyperpolarizing the postsynaptic neuron. This response can lead to the generation of an action potential if the threshold is reached, propagating the signal further along the neuron.
Are action potential and local potential reversible?
Under normal circumstances action potential will proceed unilaterally. An action potential cannot proceed down an axon and depolarize in the reverse direction on the same axon. It must carry information on one axon in one direction and then on another axon in a separate direction. In a lab you can depolarize neurons in the middle of an axon and it will depolarize bilaterally.
Where do most action potentials originate?
Action potentials most commonly originate in the axon hillock of a neuron, which is located near the cell body. This region has a high density of voltage-gated ion channels that are responsible for generating and propagating the action potential down the axon.
