What's the difference between pulsation and throb?

Pulsation


Definition:

  • (n.) A beating or throbbing, especially of the heart or of an artery, or in an inflamed part; a beat of the pulse.
  • (n.) A single beat or throb of a series.
  • (n.) A stroke or impulse by which some medium is affected, as in the propagation of sounds.
  • (n.) Any touching of another's body willfully or in anger. This constitutes battery.
