WitrynaNerve impulses are action potentials that travel along membranes. The voltage of nerve impulses is approximately +30 mV. Upon completion of the action potential, the sodium-potassium pump begins to operate. Repolarization will ultimately result in a resting potential for the axon membrane. In reverse order, the process occurs now. Witryna12 lut 2004 · Over half of all the nerve cells in your nervous system do not transmit any impulses.

WitrynaWhen the nerve impulse arrives at the synapse, it may cause the release of neurotransmitters, which influence another (postsynaptic) neuron. The postsynaptic neuron may receive inputs from many additional neurons, both excitatory and inhibitory.
