General Information
Term type II motor neuron of sperm storage organ ID (Ontology) FBbt:00052017 (Fly Anatomy)
Definition Motor neuron that innervates a sperm storage organ (spermatheca or seminal receptacle) with octopaminergic type II terminals (Avila et al., 2012). The seminal receptacle is innervated in the region proximal to the uterus and the spermathecal duct is innervated mainly in the distal third (Avila et al., 2012).[ FlyBase:FBrf0217828 ]
Comment Octopaminergic type II boutons identified based on bouton morphology and Tdc2-GAL4 expression (Avila et al., 2012). Not clear from Avila et al. (2012) whether each cell innervates both organs or whether there are subpopulations.
