Morphology

pulsatility = pulsatile (semi-transparent) = pulse + ity

Formed by adding the noun-forming suffix '-ity' to 'pulsatile'; the morphological pattern is regular but 'pulsatile' is specialized technical vocabulary.

Etymology

Pulsatility comes from pulse, meaning 'a regular beat' like your heartbeat, and the ending -ity, meaning 'state'. So, pulsatility is the 'state of having beats' or regular rises and falls, which is why doctors use it to talk about blood flow or hormone release.
