General Information
Term caudal vesicle of iSNSP ID (Ontology) FBbt:00001074 (Fly Anatomy)
Definition One of the three iSNSP pouches at embryonic stage 12, located in a intermediate position. It has around 25 cells. At stage 15, it has lost its epithelial structure and forms a cluster of cells. Half of these cells remains at the junction between the esophagus and proventriculus and develop into the proventricular ganglion. The other half migrates dorsally and anteriorly along the esophagus and possibly contributes to the frontal and/or hypocerebral ganglion.[ FlyBase:FBrf0078614 ]
Also Known As"caudal pouch of iSNSP"
