A series of closely spaced annulations surround the surface of the body of Batracobdella picta. The epidermis is covered by a thin cuticle which is composed of several layer of orthogonally arranged, fibrous bundles. Numerous fine projections carpet the surface of the cuticle and appear to be derived from microvillar processes which extend through the cuticle from subjacent epithelial cells. Septate junctions occur between adjacent epithelial cells, and hemidesmosomes with associated tonofilaments appear to anchor the epithelium to the overlying cuticle and to the basal connective tissue. The epithelial cells contain abundant organelles including granular endoplasmic reticulum, mitochondria and Golgi complexes. The cytology of the body wall of B. picta is compared with that of other annelids.
一系列紧密排列的环纹围绕着彩纹蛭身体的表面。表皮被一层薄的角质层覆盖,该角质层由几层正交排列的纤维束组成。角质层表面布满了许多细小的突起,这些突起似乎源自微绒毛突起,它们从下方的上皮细胞穿过角质层延伸出来。相邻上皮细胞之间存在分隔连接,带有相关张力丝的半桥粒似乎将上皮细胞固定在上覆的角质层和基底结缔组织上。上皮细胞含有丰富的细胞器,包括颗粒内质网、线粒体和高尔基体。将彩纹蛭体壁的细胞学特征与其他环节动物的进行了比较。
