General Information

Term

lesA neuron

ID (Ontology)

FBbt:00002012 (Fly Anatomy)

Definition

Sensory neuron of the larval peripheral nervous system that innervates a lateral external sense (les) organ. These neurons are found in the thoracic and abdominal segments and they are the ventralmost les neurons (Dambly-Chaudiere and Ghysen, 1986).[ FlyBase:FBrf0045359 FlyBase:FBrf0046281 FlyBase:FBrf0089570 ]
