The word constrictor comes from the Latin terms con meaning “together” and the verb stringere meaning “to bind.” The word pharynx, what is referred to as the throat, arises from the Greek pharangos meaning “cleft, gulley, or ravine.” The Latin word superior comes from the Latin superus meaning “upper.”
