ID (Ontology)

FBbt:00001722 (Fly Anatomy)

Definition

A cluster that surrounds the aorta, dorsal to the esophagus. It is composed of the corpus allatum (CA), corpus cardiacum (CC) and the prothoracic gland in the larva and the CA, CC and hypocerebral ganglion in the adult (Hartenstein, 1993). In the larva it is found anterior to the brain (Dai and Gilbert, 1991). The gland migrates posteriorly during pupal stages and the larval prothoracic gland degenerates (Dai and Gilbert, 1991). In the adult it is found posterior to the brain, just anterior to the proventriculus (Nassel and Zandawala, 2020).[ FlyBase:FBrf0053727 FlyBase:FBrf0064803 FlyBase:FBrf0089570 FlyBase:FBrf0179777 FlyBase:FBrf0239029 FlyBase:FBrf0247015 ]
