Abstract

Abstract

The digestive system of Cymatium pileare consists of buccal cavity,oesophagus,stomach,intestine, anus,salivary gland and liver.There is a contractible "argobuccinum" form proboscis in the anterior extremity of its body,and the buccal cavity lies in the anterior part of the proboscis.There are a pair of jaws and a piece of radular ribbon in buccal cavity.The jaws have many neatly arranged sickle-shaped sharpen denticles.The dentition formula of radula is:2·(7)1·(5~6)1(5~6)·1(7)·2.In the middle of oesophag us,there is an expanded crop,which has the function of temporarily storing food and preliminarily digesting food.The stomach is U-shaped and there are 2 entrances for liver ducts in its ventral side.The intestine is short and can be divided into 2 parts based on the struture of epithelia of their inner walls.The inner wall of for eintestine is stratified columnar epithelium,but the inner wall of hindintestine is pesudostratified columnar epithelium.The salivary gland of C.pileare is toxic gland and the tox in extracted from it plays a great role on its predation.The liver of C.pileare is compound tubuloacinar gland with mitochondrion,rough endoplasmic reticulum,Golgi complex and lysosome in its glandular cells.
