中文摘要：

对凹耳臭蛙Odorrana tormota消化系统进行了解剖学及组织学观察。消化道可以分为口腔、咽、食道、胃、十二指肠、回肠和直肠，末端开口于泄殖腔。肝脏和胰腺为消化腺。消化道管壁的组织结构均为4层结构，由管腔向外依次为黏膜层、黏膜下层、肌层和浆膜。胃黏膜层中含有许多胃腺，可明显分为腺颈部和腺体部。小肠含有十二指肠腺，直肠含有直肠腺。肝脏发达，分为左、中、右3叶，肝小叶界限不明显。胰腺中的腺泡由腺细胞围成。凹耳臭蛙肠全长与头体长之比为0．44～0．91，是迄今为止报道的无尾两栖类中最小的。

英文摘要：

The digestive system of Odorrana tormota has been anatomically and histologically studied. The results show that, the digestive tract consists of the mouth cavity, pharynx, esophagus, stomach, duodenum, ileum, rectum and the end- most openings in the cloaca; and the alimentary glands include the liver and the pancreas. The digestive tract wall is com- posed of four layers which are the mucosa, submucousa, muscularis, and serosa. Gastric glands, evidently consisting of the neck and the body, are abundant in the mucosa. The intestinal glands include the Brunner＇s gland and the rectal gland. The liver is obviously divided into three lobes which are left, middle and right lobes, and the boundaries among hepatic lobules are not distinct. The acinus of the pancreas is surrounded by acinus cells. The ratio of the total length of intestine to the snout-vent length is 0. 44 -0. 91, which is the minimum for tailless amphibians so far.
