Etymology
Origin: Latin
Borrowed from French carotide or New Latin carōtides, from Ancient Greek κᾰρωτῐ́δες (kărōtĭ́des, “carotid arteries”), from κᾰρόω (kăróō, “to plunge into deep sleep or torpor”) + -τῐ́δες (-tĭ́des, plural nominal suffix), from the fact that the carotid artery supplies blood to the brain, and interruption of this flow causes loss of consciousness.
