Figure 3
TEM micrographs of the salivary gland in adult male C. megacephala. (a) Salivary gland cells highlighting the basal lamina (bl), and infoldings of the basement membrane (arrows). Evidence of small tracheole (tr) insertion. Bar = 1 μm. (b) The gland cell cytoplasm showing aggregation of the oval reservoir of secretory materials (arrows). Bar = 1 μm. (c) Secretory reservoirs containing electron dense secretory granules (arrow). Bar = 2 μm. (d) Aggregation of secretory reservoirs (arrows). Bar = 0.5 μm. (e) Variable secretory reservoir (arrows). Bar = 0.2 μm. (f) Secretory reservoir demonstrating globulin-like material (arrow). Bar = 1 μm.
