Term calyx of larval mushroom body ID (Ontology) FBbt:00007191 (Fly Anatomy)
Definition Calyx of the larval mushroom body. It contains dendrites of the larval Kenyon cells (Masuda-Nakagawa et al., 2009; Saumweber et al., 2018). It is organized into around 34 glomeruli, each innervated by a single projection neuron (Masuda-Nakagawa et al., 2009).[ FlyBase:FBrf0208205 FlyBase:FBrf0238440 ]
