摘　　要：运用组织学方法对池蝶蚌不同部位外套膜进行了研究。结果表明,池蝶蚌外套膜由边缘膜和中央膜组成,边缘膜包括3个突起,分别是生壳突起,感觉突起和缘膜突起。不同部位外套膜的组织结构基本相同,由外表皮、内表皮和结缔组织组成。内表皮细胞间分布有3种类型的分泌细胞,分别是嗜碱性粘液细胞、大分泌颗粒细胞、小分泌颗粒细胞。外表皮上分布一种空泡状分泌细胞。不同部位边缘突起的形状、面积等有较大差异。不同部位外套膜的厚度也不同,一般是蚌体中部和中后部外套膜较厚。The histological structure of the mantle in 4 regions of Hyriopsis schlegeli was observed. The typical structure of the mantle of shell consists of a middle zone and a marginal zone. Three protuberances are observed in the marginal zone, which are shell protuberance, sensory protuberance and velum protuberance. The structures of the mantle in different regions are similar, composed of inner epithelium, outer epithelium, connective tissue and muscular fiber. Three kinds of secretory cells are distributed in the inner epithelium and connective tissue ,while one kind in the outer epithelium. The shape and size of the three protuberances in various regions have great differences. The thickness of the main part of mantle marginal zone is not same,while the central and the posterior parts are thicker.
