An ampulla (plural "ampullae") was, in Ancient Rome, a "small nearly globular flask or bottle, with two handles" (OED). The word is used of these in archaeology, and of later flasks, often handle-less and much flatter, for holy water or holy oil in the Middle Ages. *Monza ampullae - 6th century, metal souvenirs of pilgrimages to the Holy Land. *Holy Ampulla - glass, part of the French coronation regalia and believed to have divine origins. *The Ampulla in the British Crown Jewels, a hollow, gold, eagle-shaped vessel from which the anointing oil is poured at the Coronation of the British Monarch. ==Medicine and science== *By extension, in scientific contexts, ampulla may mean a dilated segment in a tubular structure. It is used to describe several anatomical structures: * *Ampullae of Lorenzini – electroreceptors in fishes * *Ampulla of uterine tube (ampulla tubae uterinae) * *Ampulla of ductus deferens (ampulla ductus deferentis) * *Cisterna chyli (ampulla chyli) * *Duodenal ampulla or duodenal cap (ampulla duodeni) – the very first part of the duodenum, which is not retroperitoneal. * *Hepatopancreatic ampulla, also called ampulla of Vater * *Rectal ampulla (ampulla recti) * *Osseous ampullae (ampulla ossea) – in the semicircular canals of the mammalian ear * Ampullae are also bulb-like structures above the tube feet in echinoderms, and in arthropod male genitals. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ampulla (disambiguation)」の詳細全文を読む スポンサード リンク
