Resting Potential At rest the cell membrane is polarized maintaining a negative interior charge of -70mv. This is called the electrical gradient. There is about ten times more sodium (Na+) on the outside and twenty times more potassium (K+) on the inside.

An action potential (or nerve impulse ) is a transient alteration of the transmembrane voltage (or membrane potential) across an excitable membrane in an excitable cell (such as a neuron or myocyt...

The auditory hair cell resting potential is critical for proper translation of acoustic signals to the CNS, because it determines their filtering properties, their ability to respond to stimuli of both polarities, and, because the hair cell drives afferent firing rates, the resting potential dictates spontaneous transmitter ...

The Medscape Journal ... Allergy & Clinical Immunology ... The mean RP was approximately--60 mV and the mean MEC was approximately 39 pF. Sodium salicylate could decrease RP and MEC, which possessed a dosage-effect relation, that is, the effect was stronger in higher concentration than in lower concentration, and there was no...

Resting Membrane Potential ... The resting potential tells about what happens when a neuron is at rest. An action potential occurs when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a "spike" or an "impulse" for the action potential.

Given that the membrane is permeable only to certain ions (e.g., K+), these forces create what is called a resting potential. ... These simple rules create the resting potential: ... In other words, the resting potential has the inside of the neuron 70mV more negative than the extracellular space (V stands for voltage).

In this tutorial, we review how ion channels are responsible for a voltage difference (called the resting potential) across the plasma membrane of a neuron. Click on the ANIMATION tab to review the ionic basis of the resting membrane potential.
