Classification
Nouns denoting natural events.
Examples
- The nervous impulse traveled rapidly down the length of the axon, transmitting the signal to the next neuron.
- The researchers studied the nervous impulse patterns in the brain to better understand the neural mechanisms underlying decision-making.
- A nervous impulse is generated when the membrane potential of a neuron reaches a certain threshold, triggering an action potential.
- The speed of the nervous impulse was measured using electroencephalography, revealing a significant delay in the transmission of signals.
- The nervous impulse that controls muscle contraction is initiated by the release of neurotransmitters from the terminal end of a motor neuron.
