Etymology: "Tentoriums" is the plural of "tentorium", a term for the tent-like fold of tough membrane that separates the cerebrum from the cerebellum in the skull. The anatomical sense is a borrowing of the Latin noun "tentorium", which literally means "tent", coined in the early 19th century when anatomists needed a name for this structure. The Latin word is itself a derivative of "tendere", "to stretch", the same verb behind English "tend" and "tension" and the root of "tent" itself, so the anatomical term describes the membrane as a stretched canopy over the lower brain. The plural "tentoriums" is the form most English writers use, following the regular English pattern, though Latin "tentoria" also appears in technical writing.

Synonyms: tentorium, membrane, partition, septum, structure
