| 摘 要： | 对王锦蛇（Ｆｌａｐｈｅｃａｒｉｎａｔａ）尿殖系统的各个器官进行组织学研究的结果表明：其肾脏主要由肾单位和集合管构成，输尿管分粘膜层、肌层和外膜。卵巢外被生殖上皮，内为结缔组织构成。输卵管在形态结构上有前、中、后段的差异，睾丸外被结缔组织膜，内为曲细精管，小管内含有不同发育阶段的生殖细胞。副睾被睾丸系膜与睾丸包裹在一起，内含副睾管，输精管分粘膜层、肌层和外膜，交接囊各段的组织结构不同，远端有类似于哺乳类阴茎的海绵体和血窦，体现了爬行类与哺乳类有渊源关系。

| Abstract: | The kidnery consists of renal unit and collecting duct. Ureteris is constituted by mucous men-brane,muscle layer and external membrane.The exterior part of ovary is reproductive epithelium andinterior is con nective tissue. The different part of oviduct has morphological difference.The exterior oftestis is connective tissue membrane and interior is seminiferous tubules.The exterior epididymis is testismembrane and interior is epididymal duct.Vas deferens consists of mucous membrane,muscle layer andserous mem brane.Different part of petasma has differente tissue structure. |
