What else can I help you with?
What has to be crossed before the neuron fires?
The threshold potential must be reached for the neuron to fire. This is the level of depolarization that triggers an action potential to be generated and propagated 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.
The process of depolarization and repolarization is called?
The process of depolarization and repolarization is called an action potential. During depolarization, the cell's membrane potential becomes more positive, while during repolarization, the membrane potential returns to its resting state.
When does arterial depolarization occur?
Arterial depolarization occurs when action potentials are generated in the cardiac cells of the heart during the electrical conduction system, leading to the contraction of the heart muscle. This depolarization occurs as the electrical signal travels through the atria and then the ventricles, causing them to contract and pump blood.
Why is an action potential is self-regenerating?
An action potential is self-regenerating due to the depolarization phase, where sodium channels open in response to membrane depolarization, leading to an influx of sodium ions that further depolarizes the membrane and triggers adjacent sodium channels to open. This positive feedback loop allows the action potential to propagate along the axon without losing strength.
Action potential will be propagated only after a sufficiently large resting membrane potential has been achieved in the direction of?
depolarization
What has to be crossed before the neuron fires?
The threshold potential must be reached for the neuron to fire. This is the level of depolarization that triggers an action potential to be generated and propagated along the neuron.
What is the only muscle that can contract itself?
The heart is self-contracting or rather it has a high susceptibility to depolarization.
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.

How is depolarization in a hair cell different from depolarization in a typical neuron?
Depolarization in a hair cell is triggered by mechanical stimulation, such as sound waves or movement, while depolarization in a typical neuron is triggered by chemical signals.
Is depolarization the resting state of the p wave?
No, depolarization is not the resting state of the P wave. Depolarization is the process where the heart muscle contracts in response to an electrical signal. The P wave represents atrial depolarization, the electrical activity that triggers the contraction of the atria in the heart.
Can Cistus be propagated by amateurs?
Yes. Cistus can be propagated by seeds or cuttings and is easy to propagate.
What do radio waves propagated through the interaction of?
radio waves are propagated through the interaction of
What is an antonym for polarization?
Depolarization
What ion channel enables depolarization?
Voltage-gated sodium channels enable depolarization in excitable cells by allowing an influx of sodium ions, which leads to the rapid depolarization phase of an action potential.
The greater influx of sodium ions results in what of the membrane?
The greater influx of sodium ions results in membrane depolarization. This is because sodium ions carry a positive charge, which leads to a decrease in the membrane potential towards zero or a positive value.
