摘　　要：应用光学显微镜和电子显微镜技术,研究了中华绒螯蟹(Eriocheir sinensis)胸神经团的神经分泌细胞,描述了其显微和超显微结构。依据细胞形态、细胞核、内分泌颗粒和细胞质的特征将胸神经团神经分泌细胞分为3种类型:Ⅰ型细胞最大,胞质中存在许多大小不同的空泡,分泌颗粒数量很少;Ⅱ型细胞中等大小,细胞器发达,分泌颗粒数量较多,形态多样;Ⅲ型细胞最小,分泌颗粒数量最多,细胞器很少。Neurosecretory cells in the thoracic nerve regiment of Eriocheir sinensis were investigated with light microscopy and electron microscopy. According to the cell shapes and the features of nucleus, secretory granules and cytoplasm, the neurosecretory ceils in the thoracic nerve regiment were divided into three types：type Ⅰ cells are 50 - 145 μm in diameter with many vacuoles and few neurosecretory granules;type Ⅱ cells are 27 - 53 μm in diameter with many developed organeUe and various neurosecretory granules; and type Ⅲ cells are 7 - 19 μm in diameter with few organeUe and abundant neurosecretory granules.
