Figure 2: Micrographs of the salivary gland in adult male C. megacephala. (a) Light micrograph of the thick section showing the narrow central gland lumen. Arrows indicate a large nucleus. Bar = 5 μm. (b–d; TEM micrographs) (b) Compartment of the gland context (arrows). Bar = 5 μm. (c) Baso-lateral region of the gland cell, exhibiting infoldings of the basement membrane (arrow). A large nucleus (n) is observed. Bar = 1 μm. (d) Interdigitation of cytoplasmic extensions between the adjacent gland cells (arrows). Bar = 1 μm.
