Fig. 3. Two large salivary neurones (SN1 and SN2) in the suboesophageal ganglion (SOG), stained by metal backfilling of one salivary duct nerve (SDN), viewed dorsally (A) and laterally (B). Areas surrounded by broken lines are mandibular (MD), maxillary (MX) and labial (LB) neuromeres, respectively. CC, cervical connective; COC, circumoesophageal connective. (C) An SDN at the surface of a salivary duct (SD), filled with metal. The broken line indicates the outline of the SDN. Two large-diameter axons (black arrowheads) and one small-diameter axon (white arrowhead) are visible. SG, salivary gland; A, anterior; P, posterior; V, ventral; D, dorsal.
