Repolarization of a ventricular cardiocyte taks longer then repolarization of a typical neuron?
yes
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.
Corresponds to the period of repolarization of the neuron?
Action Potential
The diffusion of potassium out of a neuron causes it to experience?
repolarization
What is the period which potassium ions are diffusing out of the neuron?
repolarization
_____ is the process by which the neuron regains its negative resting membrane potential?
Repolarization
What is The depolarization and repolarization of a neuron membrane called?
This process is called nerve conduction.
What effect does the opening of the potassium channels have on the charge difference across the neuron's membrane?
repolarization
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.
What changes occur in the neuron?
Neurons undergo depolarization and repolarization when stimulated. The sodium and potassium channels open.
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.
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
