| 摘 要： | 为进一步探讨甲壳类光感受器的结构和功能,采用石蜡切片技术对虾蛄复眼组织结构进行了研究.分析发现虾蛄复眼呈短棒状,由折光系统、感光系统和反光系统组成.折光系统包括角膜和晶锥.感光系统由6个远端小网膜细胞和7个近端小网膜细胞构成,彼此之间通过突起相连接.感杆束较短,为闭合型.反光系统由色素组成.近端小网膜细胞之间分布有一种合胞体细胞,可能也有感光功能.

Histological Characteristics of the Photoreceptor of Oratosquilla oratoria |

| Abstract: | In order to investigate the structure and function of the photoreceptor of crustaceans, the histomorphology of compound eyes in Oratosquilla oratoria was studied by paraffin biopsy technology.The eyes of O.oratoria were short rod-shaped and made up of refractive systems, sensing systems and reflective systems.The refractive system consisted of the cornea and crystalline cone.The sensitization system was composed of 6 distal retinular cells and 7 proximal retinular cells.They kept in touch with each other by protrusions.The rhabdom of the ommatidia was short and closed-type.The reflective system consiseds of pigment ingredients.A kind of syncytial cell was distributed among proximal retinular cells, it may also have a photosensitive function. |
