resting potential

That original state is referred to as the resting potential.

Until this resting potential has been attained which takes about 0.0004 seconds no further impulse can be passed along the fibre.

In most neurons the resting potential has a value of approximately -70 mV.

If we assume the resting potential is 0.

The resting potential is not affected by these pyrethroids.

On the other hand, the high resting potential in undifferentiated cells can be a metabolic advantage.

The interactions that generate the resting potential are modeled by the Goldman equation.

In this case, the resting potential can be determined from the Goldman equation:

The normal resting potential of ventricular myocytes is approximately -90mV.

Neurons have a resting potential of about -70mV.

Consequently, the resting potential is usually close to the potassium reversal potential.

Rythmogenesis in a neuron is due to an instability associated with the resting potential.

The opening and closing of ion channels can induce a departure from the resting potential.

Cells may draw on the energy they store in the resting potential to drive action potentials or other forms of excitation.

The resting potential will not be restored, and no further action potential can be generated.

In health a cell membrane has a resting potential of around + 90 mV (millivolts).

However, a real cell is more complicated, having permeabilities to many ions, each of which contributes to the resting potential.

Typically, the amount of certain potassium channels is most important for control of the resting potential (see below).

O.G.) is a technique for measuring the resting potential of the retina.

Without this negative resting potential, cardiac cells cannot repolarize (prepare for their next contraction).

The resulting increase in potassium efflux which hyperpolarizes the cell and the resting potential is lower.

This apparent paradox is resolved by examination of the origin of that resting potential.

The resting potential for potassium-sodium channels in a neuron is about -65 millivolts.

In most cells the resting potential has a negative value, which by convention means that there is excess negative charge inside compared to outside.

As the frequency of stimuli increases, there is less time between each stimulus for the cell to repolarize and return to normal resting potential.
