林麝消化器官的解剖

DISSECTION OF DIGESTIVE ORGANS OF M. BERZOVKII

运用大体解剖学方法，对三头林麝的消化器官进行了研究，并与牛羊的消化器官进行了比较。林麝软腭长；雄性具有发达的上犬齿；瘤胃后背盲囊伸向左下方，后腹盲囊伸向右上方；网胃粘膜形成的网格皱褶极低，不形成次级网格；瓣胃粘膜的瓣叶少；结肠初长，旋袢管径粗细不等，胆管与胰管合并成一条总的胆胰管。

The digestive organs of three m. berezovskii were studied and compared with those of oxen and goats with the general dissecting method. The characteristics of the digestive organs of the m. berezovskii were as follows:Soft palate was long. The cranial groove and caudal groove of rumen was deep. Caudodorsal blind sac extended to left and caudoventral blind sac extended to right. In the reticulum, the mucous membrane is raid into fould, which enclose four-, five-, or six-sided cells. But the cells were not subdivided by small folds.The cavity of the omasum is occupied by 21-24 longitudinal folds. The proximal loop of aseending colon was long. The distance from the bottom of gallbladder to the ventral border of the livet was 1. 28-1. 63cm. Pancteatic duct jioned bile ductbefore it reached duodenum.
