克氏原螯虾触角腺的组织学研究

HISTOLOGICAL STUDY ON THE ANTENNAL GLAND OF FRESHWATER CRAYFISH,PROCAMBARUS CLARKII

本文利用石蜡切片技术对克氏原螯虾触角腺进行了组织学研究。结果表明，克氏原螯虾触角腺可分为端囊、迷路和肾管三部分。端囊部分的细胞呈柱状，细胞核位于基部；迷路部分细胞也呈柱状，其顶端具刷状缘，核位于细胞的基部或中部，迷路部分可分为二个亚区；肾管部分的细胞呈柱状或较为扁平，核位于细胞的中部或靠近细胞顶端，肾管部分可分为三个不同亚区。

Histological method has been used to study tha antennal gland of crayfish Procambarus clarRii.The result shows that there are three regions in the antennal gland:coelomosac,labyrinth and nephridial canal.Cells in coelomosac region are elongated and enlarged apically,and flocculent cytoplasmic extrusions are found projecting into the lumen on the apical margin of the cells;the nuclei are located basally. In labyrinth region all cells are columnar with brush border apically and basally or eccentri.cally located nuclei.Labyrinth region can be divided into two subregions.All cells in nephridial canal are columnar or flat and their neclei are located apically or eccentrically.Nephridial canal can be divided into three subregions.
