Fig. 8

TEM micrographs of Dibothriocephalus latus plerocercoids depicting gland-cells and their ducts. Secretory ducts of the gland-cell going towards the distal cytoplasm (a, b). The nucleus and cytoplasm of gland-cell with extensive granular endoplasmic reticulum, secretory granules and vacuoles (c). A longitudinal section through the ducts filled with secretory material. Note a large reservoir formed from dilatation of the duct with great numbers of secretory granules (d). Detail of the secretory granules; note their moderately-dense cores (e). Abbreviations: GER, granular endoplasmic reticulum; LD, lipid droplets; LM, longitudinal muscles; N, nucleus; SD, secretory duct; SG, secretory granules; R, reservoir; V, vacuoles
