General Information
Term corpus cardiacum ID (Ontology) FBbt:00005799 (Fly Anatomy)
Definition Neuroendocrine structure that forms part of the ring gland. In the embryo and larva it is found around the floor of the aorta, just anterior to the brain (Dai and Gilbert, 1991; de Velasco et al., 2004, Nassel and Zandawala, 2020). It migrates posteriorly during metamorphosis (Dai and Gilbert, 1991) and is found posterior to the brain, near the proventriculus, in the adult (Nassel and Zandawala, 2020). It produces Adipokinetic hormone from late embryo to adult stages (Lee and Park, 2004).[ FlyBase:FBrf0053727 FlyBase:FBrf0089570 FlyBase:FBrf0178933 FlyBase:FBrf0247015 ]
