Etymology
the word pulsation originates from the latin verb pellere, meaning "to drive, push, or strike." its past participle form, pulsus, gave rise to the latin noun pulsatio, which denoted a beating or striking action. this concept was borrowed into middle english via old french, carrying the sense of a throbbing or beating motion. the modern english term retains this core logic, where the morpheme 'puls' conveys the idea of a driving force or beat, and the suffix '-ation' transforms it into a noun describing the process or result of that action, specifically a rhythmic beating or vibration.
