General Information
Term larval corpus cardiacum-innervating Hugin neuron ID (Ontology) FBbt:00007468 (Fly Anatomy)
Definition Larval neuron that expresses Hugin and whose soma is located in the cortex of the medial subesophageal ganglion, just below the esophageal foramen (Siegmund and Korge, 2001; Schlegel et al., 2016). It projects to the ring gland, where it has peptide release sites in the corpus cardiacum and aorta (Siegmund and Korge, 2001; Huckesfeld et al., 2021). The vast majority of its synaptic inputs are in the subesophageal zone, from interneurons, and it does not have synaptic outputs within the central nervous system (Schlegel et al., 2016). There are two of these cells per hemisphere (Siegmund and Korge, 2001; Schlegel et al., 2016).[ FlyBase:FBrf0134726 FlyBase:FBrf0200884 FlyBase:FBrf0214320 FlyBase:FBrf0234450 FlyBase:FBrf0249161 ]
Also Known As "CC-MS 1" ; "corpus cardiacum innervating neuron CC-MS 1" ; "hugin neuron of the ring gland" (for all, see Synonyms field below)
