What event follows after the depolarization of a neuron?
After depolarization, the neuron undergoes repolarization, during which the cell's membrane potential returns to resting state. This is followed by hyperpolarization, where the membrane potential briefly becomes more negative than the resting state, before returning to its baseline. Finally, the neuron enters a refractory period, during which it is temporarily unable to generate another action potential.
What is the rapid change in a membreanes potential cause by the depolarization of a neuron?
The rapid change in membrane potential caused by the depolarization of a neuron is known as an action potential. During depolarization, voltage-gated sodium channels open, allowing sodium ions to flow into the cell, causing the inside of the neuron to become more positive. This shift in charge initiates the action potential, which is essential for the transmission of electrical signals along the neuron.
What is self propagated depolarization?
Self-propagated depolarization refers to the process by which an action potential triggers the opening of voltage-gated ion channels along the membrane, causing further depolarization in adjacent regions of the neuron. This process allows the action potential to travel down the length of the neuron, enabling rapid communication within the nervous system.
What is depolarization of a neurotransmitter?
Depolarization of a neurotransmitter refers to the shift in the electrical charge of the neuron, making it more likely to generate an action potential. This can occur when a neurotransmitter binds to its receptor on the postsynaptic membrane, causing ion channels to open and allowing the influx of positively charged ions. This depolarization triggers a series of events that lead to the transmission of the nerve signal.
State in which the resting potential is reversed as sodium ions rush into the neuron?
This state is known as depolarization. It occurs when there is a rapid influx of sodium ions into the neuron, causing the inside of the neuron to become more positively charged compared to the outside.
Opening of sodium channels in the membrane of a neuron results in?
depolarization.

What is The depolarization and repolarization of a neuron membrane called?
This process is called nerve conduction.
What happens when sodium enters a neuron?
When sodium enters a neuron, it triggers depolarization of the cell membrane, which leads to an action potential being generated. This action potential then travels along the neuron, allowing for communication between different neurons or between a neuron and a muscle cell. Sodium influx is a key step in the process of nerve signal transmission.

This process allows the action potential to travel down the length of the neuron, enabling rapid communication within the nervous system.
What event follow the depolarization of neuron?
Repolarization is after depolarization. It descends to a region of hyper polarization where it is more polar than resting membrane potential
What is depolarization of a neurotransmitter?
Depolarization of a neurotransmitter refers to the shift in the electrical charge of the neuron, making it more likely to generate an action potential. This can occur when a neurotransmitter binds to its receptor on the postsynaptic membrane, causing ion channels to open and allowing the influx of positively charged ions. This depolarization triggers a series of events that lead to the transmission of the nerve signal.
Which is the first step in a neuron production of an action potential?
Depolarization is the first event in action potential. During depolarization, the sodium gates open and the membrane depolarizes.
State in which the resting potential is reversed as sodium ions rush into the neuron?
This state is known as depolarization. It occurs when there is a rapid influx of sodium ions into the neuron, causing the inside of the neuron to become more positively charged compared to the outside.
Why is the resting membrane potential the same in both the sensory neuron and the interneuron?
Because it didnt have a stimulus to activate depolarization
What does it mean when a cell is depolarized?
Depolarization refers to the reversal of charges of neuron cell membrane, it occurs by moving in of 'Na' ions .
