Figure 4 Ventral podocephalic glands in unfed larvaeL. maculata. TEM. a – General view of the gland bordering the anterior medial gland and the brain. Note flat margins of the gland facing neighboring organs (arrows). Scale bar – 5µζ; b – Border of the ventral and the anterior medial glands showing flat basal plasma membranes with the absence of the noticeable basal lamina (arrows). Arrowheadspoint to microvilli on the apical cell surface facing the intra-alveolar lumen. Note that the duct –forming cells also bears microvilli interdigitating within the lumen. Scale bar – 1µζ. amg – anterior medial gland; br – brain; cv – clear vesicles; dfc – duct-forming cell; ial – intra-alveolar lumen; n – nucleus; sg – secretory granules; vg – ventral gland.
