果子狸消化器官的解剖研究

ANATOMICAL STUDIES OF THE DIGESTIVE APPARATUS IN Paguma larvata

为了解果子狸消化系统各器官的解剖结构及消化生理，为人工养殖提供科学依据，对１６只成年果子狸（♀７只，♂９只）消化系统进行了大体解剖和实体显微观察．果子狸的胃呈侧卧的“Ｕ”字形，且上半部较大，为大容量部，下半部较小，为小容量部；胃部组织具有很大的伸缩性．小肠相对较短，约为体长的５倍．大肠的结肠特别短，仅１０．２ｃｍ，且不形成结肠袢，直接与直肠相连；盲肠不发达．肝、胰也各呈现出独特的解剖特征．

The digestive apparatuses of 16 adult P.larvata (7 female,9 male) were observed in detail.Their stomaches look like letter “U”.The upper part of the stomaches was larger than the lower part,and therefore the upper and lower parts were called “largevolume part”and “smallvolume part”,respectively. The stomach walls were flexible. The intestinum tenue was about 5 times as long as the body. The colons were only 102 cm long,did not have ansa colons,and directly connected with the recta. The caeca were undeveloped.Both the livers and pancreas had a unique anotomical feature as well.
