2 Physiology The prolonged contraction of a muscle caused by rapidly repeated stimuli.
Example sentences

  • At 50 shocks per second, the muscle goes into the smooth, sustained contraction of tetanus.
  • As we normally use our muscles, the individual fibers go into tetanus for brief periods rather than simply undergoing single twitches.



Pronunciation: /ˈtetnˌīz/
Example sentences

Pronunciation: /-ˌoid/
Example sentences
