nerve impulse

A neuron transmits a nerve impulse to another neuron.

Definition
  1. Noun:
    • A brief electrical signal that travels along a neuron: A "nerve impulse" is the fundamental means of communication within the nervous system, involving a rapid, self-propagating change in electrical potential across a nerve cell's membrane.
Usage
  • The term "nerve impulse" is used to describe the electrochemical event that carries information through the nervous system. It is a technical term common in biology, physiology, and medicine.
  • It is typically used in singular or plural form to discuss the transmission of signals.
Examples
  • Noun:
    • The speed of a nerve impulse can exceed 100 meters per second.
    • Pain is perceived when a nerve impulse reaches the brain.
    • The experiment measured the frequency of nerve impulses in response to the stimulus.
Advanced Usage
  • "Generation of a nerve impulse": Refers to the process by which a neuron initiates an action potential.
    • The influx of sodium ions is crucial for the generation of a nerve impulse.
  • "Conduction of the nerve impulse": Describes the propagation of the signal along the axon.
    • Myelin sheaths increase the speed of nerve impulse conduction.
Variants and Related Words
  • Action potential (n): This is a more specific, synonymous term for the electrical event constituting a nerve impulse.
    • An action potential is an all-or-none event.
  • Neural signal (n): A broader term that can encompass nerve impulses and other forms of neuronal communication.
  • Synaptic transmission (n): The process by which a nerve impulse is communicated from one neuron to the next across a synapse.
Synonyms
  • Action potential: The rapid rise and fall in voltage across a neuronal membrane.
  • Neural impulse: An alternative term with identical meaning.
Related Phrases
  • Transmission of impulses: The sending of nerve signals from one point to another.
    • The spinal cord facilitates the transmission of impulses between the brain and the body.
  • Propagate an impulse: To conduct a nerve signal along a fiber.
    • The axon is specialized to propagate impulses efficiently.
