FIGURE 3 in Fine Structure Of The Male Genital Systems, Spermatophores And Unusual Sperm Cells Of Saxidromidae (Acari, Actinotrichida)

FIGURE 3: TEM micrographs of vas deferens and ejaculatory duct of Bovidromus roussouwi. (a) – Composed figure showing complex structure of ejaculatory duct in cross section. Note large synspermium in dorsal chamber lined by peculiar cuticle. Arrow points to eugenital (primary) genital opening. Scale bar: 20 µm. (b) – Vas deferens. Note flat epithelium. Scale bar: 20 µm. (c) – Detail of epithelium of vas deferens with irregularly shaped microvilli. Cells contain many mitochondria and are underlain by a muscular layer. Scale bar: 2 µm. (d) – Dorsal chamber of ejaculatory duct with cuticular fringes and secretion. Scale bar: 10 µm. (e) – The ejaculatory duct is surrounded by a thick muscular layer. Scale bar: 10 µm. (f) – Eugenital opening (arrow) and accessory gland. Scale bar: 20 µm.
