General Information
Term larval A1-7-innervating VO2 motor neuron ID (Ontology) FBbt:00002199 (Fly Anatomy)
Definition RP1 motor neuron of A1-7. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the VO2 muscle (Mauss et al., 2009) via type Ib boutons. Its cell body is located in the segment anterior to the muscle it innervates (Landgraf et al., 1997). During metamorphosis, these neurons that have cell bodies in the metathoracic or abdominal 1 neuromeres are re-targeted to innervate temporary eclosion muscle VL2 and become adult persistent motor neuron 14-Ib (Banerjee et al., 2016). The abdominal 2 and 3 neurons die during metamorphosis (Banerjee et al., 2016).[ FlyBase:FBrf0064795 FlyBase:FBrf0099344 FlyBase:FBrf0208790 FlyBase:FBrf0234013 ]
Also Known As "A1-7 MN14-Ib"
Comment Innervation of muscle 14 makes this equivalent to the MN14-Ib neuron of Hoang and Chiba, 2001.
