resting potential (redirected from Cell potential)

potential /po·ten·tial/ (po-ten´shal)

1. existing and ready for action, but not active.

2. the work per unit charge necessary to move a charged body in an electric field from a reference point to another point, measured in volts.

action potential  (AP) the electrical activity developed in a muscle or nerve cell during activity.

after-potential  afterpotential.

electric potential , electrical potential potential (2).

evoked potential  (EP) the electrical signal recorded from a sensory receptor, nerve, muscle, or area of the central nervous system that has been stimulated, usually by electricity.

membrane potential  the electric potential existing on the two sides of a membrane or across the cell wall.

resting potential  the potential difference across the membrane of a normal cell at rest.

spike potential  the initial, very large change in potential of an excitable cell membrane during excitation.

resting potential

Etymology: AS, rest + L, potentia, power

the electric potential across a nerve cell membrane before it is stimulated to release the charge. The resting potential for a neuron is between 50 and 100 mV, with the excess of negatively charged ions inside the cell membrane.

resting potential,

n the electrical potential across a nerve cell membrane before it is stimulated to release the charge. The resting potential for a neuron is between 50 and 100 mV.
