part of innervates continuous with subesophageal nerve adult head adult labial nerve maxillary-labial nerve LbNv LabNv labellar nerve Mixed sensory-motor nerve that innervates the adult gnathal ganglion (GNG) (Ito et al., 2014). It contains ~195 axons from sensory cells of the labium that enter labial neuromere of the GNG and GNG motor neurons travelling to the labial musculature (Nayak and Singh, 1985; Ito et al., 2014). Proximally, it gives off branches to the rostrum and haustellum, and the labellar glands and sense organs (Miller, 1950). The labial nerve is anastomosed with the maxillary nerve (forming the maxillary-labial nerve) until the latter branches off to the maxillary palp (Nayak and Singh, 1985; Ito et al., 2014). maxillar labellar nerve LbN maxillar labial nerve fly_anatomy.ontology ventral proboscis nerve VFB:FBbt_00004028 FBbt:00004028 LN adult peripheral nervous system adult labial neuromere labial nerve adult maxillary-labial nerve
