descending neuron of the gnathal ganglion DNg24 obsolete antennal mechanosensory and motor center AMMC Db7 neuron 2016-03-04T15:53:02Z true FBbt:00111502 Obsoleted due to equivalence with DNg24 (Sturner et al., 2025 - FlyBase:FBrf0262850). Descending bilateral neuron whose cell body is located in the cell body rind on the lateroanterior region of the gnathal ganglion. The primary neurite extends posterioventromedially along the ventral edge of the gnathal ganglion and turns dorsally to arborize in the antennal mechanosensory and motor center (AMMC) zones A, B and E, saddle, gnathal ganglion and wedge. The neurite that innervates the AMMC forms a thin fiber, which projects medially and crosses the midline ventral to the esophagus. Immediately after it crosses the midline, the neurite turns ventrally to arborize in the saddle, posterior gnathal ganglion then exits the brain, projecting into the thoracic-abdominal ganglion. Postsynaptic terminals are found in the AMMC in both hemispheres. Presynaptic terminals are found in the contralateral saddle and the bilateral gnathal ganglion. fly_anatomy.ontology
