| 摘 要： | 对泰山螭霖鱼(Varicorhinus macrolepi)肠道的解剖学结构进行了研究,结果表明:泰山螭霖鱼无胃,食管之后是肠道,起始端膨大呈球状,且肠道在体腔内呈“S”型走向,肠长比(肠长与体长之比)为3.04。其肠长比(Y)与体长(X)的回归方程为Y=-0.6624+0.253x(R=0.6339)。肠道由前肠、中肠和后肠组成,肠管直径由前肠到后肠逐渐变小。

| Abstract: | Anatomy of intestine of Varicorhinus macrolepi was studied in this paper. Varicorhinus macrolepi has no stomach, esophagus is followed by intestine. The beginning of the intestine expands, the intestine travels as the route of"S" in the body cavity. The ratio of gut length to body length is 3 .04. The regression equation of the ratio( Y) of gut length to body length and the body length(x) is Y = - 0.6624 + 0.253x.The intestine includes foregut, midgut and postgut. The diameter of gut is getting thiners from foregut to postgut. |
