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) ...

nerve impulse A rapid, transient, self-propagating change in electric potential across the membrane of an axon. nervous system ...

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, ...

Hermann von Helmholtz, first to measure the velocity of nerve impulses; studied hearing and vision Alan Hodgkin & Andrew Huxley, mathematical theory of how ion fluxes produce nerve impulses Georg von Békésy, research on the human ear ...

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.

Whether a receptor is a part of a neuron or in close contact with one, all convert the energy they receive into the electrical energy of the nerve impulse by depolarizing the connecting nerve cell's membrane.

nerve cell A cell specialized to originate or transmit nerve impulses. nerve cell body The largest part of a neuron that typically contains the nucleus. nerve cord A long, compact bundle of nerve cells that is part of the central nervous system.

myelinated nerve fibres in somatic nerves, measuring 1 to 22 um in diameter, conducting nerve impulses at a rate of 6 to 120 m/sec. Please contribute to this project, if you have more information about this term feel free to edit this page ...

axon a typically long outgrowth, or process, from a neuron that carries nerve impulses away from the cell body toward target cells. B Bacillus a bacterial cell that is rod-shaped (i.e. longer than it is wide).

axon - long nerve cell processes that is capable of rapidly conducting nerve impulses over long distances so as to deliver signals to other cells ...
