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
How is the resting potential different from repolarization?
Repolarization is when the cell or neuron returns to be more negative. Depolarization is when the cell or neuron becomes less and less negative.
What changes occur in the neuron?
Neurons undergo depolarization and repolarization when stimulated. The sodium and potassium channels open.
_____ is the process by which the neuron regains its negative resting membrane potential?
Repolarization
Opening of sodium channels in the membrane of a neuron results in?
depolarization.
What effect does the opening of the potassium channels have on the charge difference across the neuron's membrane?
repolarization
When the ions are moving across the membrane during the depolarization and repolarization phases of an action potential they are moving by?
Depends on what stage you are talking about. Stimulus of sodium ions from dendrites of other neurons must reach a threshold. Once that threshold is reached, sodium ions quickly diffuse into the neuron via facilitative diffusion, depolarizing the neuron. Upon this occurring, sodium channels close and potassium ions are pumped out of the neuron via active transport, leading to repolarization of the neuron.
Period during which potassium ions diffuse out of the neuron due to a change in membrane permeability?
Membrane potential - a nerve cell set and ready to fire;"The wave of reverse polarity" i.e. sodium versus potassium trans-cell-membrane ion passaging - a nerve cell firing; andRecharge period - the regeneration time.
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.
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
Repolarization of a ventricular cardiocyte taks longer then repolarization of a typical neuron?
yes
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 .
