Definition of nerve impulse in English:

nerve impulse

nounˈnəːv ˌɪmpʌlsˈnərv ˌɪmˌpəls

A signal transmitted along a nerve fibre. It consists of a wave of electrical depolarization that reverses the potential difference across the nerve cell membranes.

- After an action potential has swept along a single nerve fibre, a second nerve impulse cannot be initiated immediately.
- This ion flow triggers a cellular response, such as continuation of a nerve impulse to another neuron or the contraction of a muscle cell.
- This is achieved by the propagation of the chemotactic signal, in a manner rather similar to the conduction of a nerve impulse.
- This separation triggers other mechanisms to send a nerve impulse to the brain.
- It is the influx of sodium into the cell that is responsible for generating an action potential, which causes depolarization and conduction of the nerve impulse.
- As a nerve impulse, or action potential, reaches the end of a presynaptic axon, molecules of neurotransmitter are released into the synaptic space.

- The whole process is under voluntary control, set in motion when a nerve impulse from the brain tells the muscle to tighten or relax.
- When a hair is touched, receptors near the hair fire, triggering a nerve impulse that signals that the hair has been moved.
- The arrival of the nerve impulse, an electrical signal, at the axon activates the influx of calcium ions through voltage-dependent ion channels in the membrane.
- Stimulation of any of these receptors results in the initiation of a nerve impulse that travels to the central nervous system.
- These vibrations then stimulate the cilia, which transmit a nerve impulse to the brain informing the shark of the location of the source.
- They have also made sure that our students who tend to know a lot about automobiles, may now comprehend very well how fast a nerve impulse may travel - in kilometres rather than in miles per hour.
- That was the real clue to the idea that it was specifically sodium conductivity which changed to cause the nerve impulse.
- ‘Insect muscles differ from animal muscles in that they do not need a nerve impulse for every contraction but instead are activated by stretch,’ said Dr Irving.
- MS occurs when parts of the covering of the brain and spinal cord are lost, which disrupts the conduction of the nerve impulse.
