Fig. 7 in Morpho-histological characterization of immature of the bioindicator midge Chironomus sancticaroli Strixino and Strixino (Diptera, Chironomidae)

Fig. 7. Micrographs of glands from the retrocerebral complex of the immature Chironomus sancticaroli. (A) Longitudinal section of the corpora allata, showing the glandular epithelium, demonstrating the cell nucleus (arrowhead); (B) longitudinal section of the prothoracic gland; (C) longitudinal section showing the region of the complex, demonstrating the anterior postcerebral gland and the small group of cells that make up the corpora cardiac; (D) detail of the anterior postcerebral gland, note the granules in their cytoplasm (arrowhead); (E) detail of the small group of cells that make up the corpora cardiaca (arrows). cc: corpora cardiaca; ga: anterior postcerebral gland; ptg: prothoracic gland, tr: trachea. Stain: Harris hematoxylin and eosin. Scale bar = 20 µm.
