| 摘要: |
| 应用石蜡切片和电镜技术对凿贝才女虫(Polydora ciliata)的形态结构进行了详细观察, 以期为多毛类分类学积累更多资料。结果显示凿贝才女虫背刚毛、腹刚毛和疣足上的刚毛围绕身体形成一个刚毛环; 第五刚节刚毛变形, 形成爪状结构。体表有大量腺细胞。身体结构相对简单, 主要由表皮、肌肉层、消化系统组成。肌肉层发达, 每一体节具一对疣足, 疣足上生有刚毛, 运动能力比较强。 |

| Abstract: |
| The morphological and anatomic characterization of Polydora ciliata was described by the histological and electron microscopy. The purpose of the study was to accumulate more material for the taxonomy of polychaeta. The results showed that the notosetae, neurosetae and setae on the parapodium formed a ring around the body. P. ciliata had a modified fifth chaetiger (chaetae-bearing segment) with specialized chaetae. The body structure of P. ciliata was relatively simple insects mainly by skin, muscle layer, and the digestive system. A large number of gland cells were concentrated in glandular fields situated in the skin. The muscle system was highly developed. The muscular parapodium could facilitate their locomotion. |
