Nerve impulse


Nerve impulses activate the release of NO from these cells.
The NO diffuses into the lantern cells and inhibits cellular respiration in the mitochondria (probably by blocking the action of cytochrome c oxidase) ...

AKA: nerve impulse
The signal that travels along the length of a nerve fiber and ends in the release of neurotransmitters. Nerve impulses are the means by which information is transmitted along the neuron and throughout the nervous system.

What is a nerve impulse? A nerve impulse, or an action potential, is a series of electrical responses that occur in the cell. (Fig. 2) With the appropriate stimulation, the voltage in the dendrite of the neuron will become somewhat less negative.

The release of neurotransmitter is triggered by the arrival of a nerve impulse (or action potential) and occurs through an unusually rapid process of cellular secretion: Within the pre-synaptic nerve terminal, ...

Changed polarity of the membrane, the action potential, results in propagation of the nerve impulse along the membrane. An action potential is a temporary reversal of the electrical potential along the membrane for a few milliseconds.
