The dictyosome (Golgi body) in the secondary spermatocyte of the cricket appears in electron micrographs as a duplex structure composed of (a) a group of parallel double-membraned lamellae and (b) a group of associated vacuoles arranged along the compact lamellae in a chain-like fashion. This arrangement of ultramicroscopic structure for the dictyosomes is strikingly comparable to that described for the Golgi apparatus of vertebrates. Accordingly, the two are considered homologous structures. Associated with the duplex structure of the dictyosomes is a differentiated region composed of small vacuoles. This is thought to represent the pro-acrosome region described in light microscope preparations. In the spermatid the dictyosomes fuse, giving rise to the acroblast. Like the dictyosomes, the acroblasts are made up of double-membraned lamellae and associated vacuoles. In addition, a differentiated acrosome region is present which, in some preparations, may display the acrosome vacuole and granule. Both the dictyosomes and acroblasts are distinct from mitochondria.
在蟋蟀次级精母细胞中的高尔基体在电子显微镜照片中呈现为一种双重结构，由（a）一组平行的双膜片层和（b）一组沿紧密排列的片层呈链状排列的相关液泡组成。高尔基体这种超微结构的排列方式与脊椎动物高尔基体的描述惊人地相似。因此，两者被认为是同源结构。与高尔基体的双重结构相关的是一个由小液泡组成的分化区域。这被认为代表了光学显微镜标本中描述的前顶体区域。在精子细胞中，高尔基体融合，产生顶体母粒。与高尔基体一样，顶体母粒由双膜片层和相关液泡组成。此外，存在一个分化的顶体区域，在某些标本中，可能会显示顶体液泡和颗粒。高尔基体和顶体母粒都与线粒体不同。
