Abstract: | Summary The ultrastructure of gill epidermal cells of Diopatra neapolitana and their relationship with blood spaces are described. The existence of a basal infolding complex, related to the blood spaces, is also reported. A possible involvement of these cells in osmoregulation and ion interchange, apart from their well-known role in respiration, is suggested.Abbreviations bc Blood cell - bi Basal infolding - bl Basal lamina - bs Blood space - ci Cilia - cu Cuticle - db Dense body - EC Epidermal cell - Gc Golgi complex - id Interdigitation - j Junction - m Mitochondria - mv Microvilli - n Nucleus - pv Pinocytotic vesicle - rer Rough endoplasmic reticulum |
