General Information
Term embryonic immature chordotonal neuron ID (Ontology) FBbt:00051426 (Fly Anatomy)
Definition Immature primary neuron that will become a larval chordotonal neuron (Valdes-Aleman et al., 2021). All of these cells in thoracic and abdominal segments undergo a rotation, from having ventrally-directed dendrites, to ventral-posterior dendrites (Gonsior and Ismat, 2019). In the ventral nerve cord, the axonal growth cones of these cells are first detected in the anteroposterior tract that the mature larval cells occupy (Valdes-Aleman et al., 2021). The immature axons extend exploratory filopodia over a larger area than that covered by the arbors of the mature axons (Valdes-Aleman et al., 2021).[ FlyBase:FBrf0243863 FlyBase:FBrf0247750 ]
Also Known As "embryonic chordotonal neuron precursor"
