| Description: | Fused neuropils in the ventralmost part of the brain. It consists of three neuromeres: the mandibular, maxillary, and labial neuromeres. It houses parts of the axon terminals via the pharyngeal and maxillary-labellar nerves as well as from the thoracico-abdominal ganglia. (Note: the region has traditionally been called the "subesopheageal ganglion (SEG/SOG)", but because a part of the cerebral ganglia (CRG) also extend below the esophagus, we here employ a newly proposed term gnathal ganglia (GNG). |
