Figure 6 in Ultrastructure of the prosomal gland complex in unfed larvae of the fresh-water mite Limnesia maculata (Müller, 1776) (Acariformes, Limnesiidae)

Figure 6 Lateral podocephalic glands in unfed larvaeL. maculata.TEM. a – Collapsed gland with apparent cisterns of endoplasmic reticulum and irregularly shaped vacuoles. Scale bar – 2 µζ; b – Portion of the gland at higher magnification showing the large nucleus and ER cisterns. Note vacuole with a fine-structures matrix (arrow). Arrowheadindicates a smooth basal cell zone. Scale bar – 1 µζ; c – Enlarged highly vacuolated gland tightly applied to ventral gland from above in longitudinal section. Scale bar – 5 μm; d – Central gland portion of the same gland indicating expanded intra-alveolar lumen. Arrows point to microvilli of the duct-forming cells. Scale bar – 1 μm; e – Duct base of the gland. Scale bar – 1 µζ. dfc – duct-forming cell; du – duct; dw – duct wall; er – endoplasmic reticulum; ey – eye; ial – intra-alveolar lumen; lg – lateral gland; m - mitochondria; mg – midgut; ms – muscle; n – nucleus; nu – nucleolus; v – vacuole; vg – ventral gland.
