摘要轮虫Habrotrocha rosa Donner的珠皮具有孔，由合胞外角质层和合胞皮下组织形成。皮下组织周围含有 3 层致密细胞质，并通过不对称的细胞膜与角质层接壤。孔壁近端像环一样变硬。这些孔通向被囊泡包围的细胞质内陷。在浓缩的细胞质层附近和下方发现了微体，这些微体被解释为微过氧化物酶体。肌肉的皮下层通过桥粒样结构与皮下组织的细胞质相连。
SummaryThe integument of the rotifer Habrotrocha rosa Donner is provided with pores and formed by an extrasyncytial cuticle and a syncytial hypodermis. The hypodermis peripherally contains 3 layers of dense cytoplasm and borders the cuticle by an asymmetric cell membrane. The wall of the pores is stiffened proximally like an annulus. The pores lead into cytoplasmic invaginations which are surrounded by vesicles. Close to and also beneath the condensed cytoplasmic layers microbodies are found, which are interpreted as microperoxisomes. Subhypodermal layers of muscles are connected with the cytoplasm of the hypodermis by desmosome-like structures.
