General Information
Term larval EL neuron ID (Ontology) FBbt:00001572 (Fly Anatomy)
Definition Larval primary interneuron that expresses even-skipped and has its soma in the ventrolateral cortex of the ventral nerve cord (Patel et al., 1989; Wang et al., 2022). It is produced by a type 0 division of neuroblast NB3-3 (Wang et al., 2022). There are approximately 5 of these cells per thoracic hemineuromere and around 9 per abdominal hemineuromere (Schmidt et al., 1997).[ FlyBase:FBrf0098344 FlyBase:FBrf0219785 FlyBase:FBrf0229965 FlyBase:FBrf0254149 ]
Also Known As "EL interneuron" ; "ELC" ; "Eve+ lateral neuron" (for all, see Synonyms field below)
