General Information
Term larval MP3 neuron ID (Ontology) FBbt:00001604 (Fly Anatomy)
Definition Larval neuron that develops from the MP3 precursor. There are two of these per segment, H-cell and H-cell sib, both are unpaired cells found at the ventral midline (Bossing and Technau, 1994; Kearney et al., 2004; Wheeler et al., 2016).[ FlyBase:FBrf0072659 FlyBase:FBrf0180108 FlyBase:FBrf0195284 ]
Also Known As"MP3 cell" ; "UMI interneuron" ; "unpaired median interneuron"
