General Information
Term pedunculus divide of adult mushroom body ID (Ontology) FBbt:00045009 (Fly Anatomy)
Definition The anterior end of the pedunculus of the adult mushroom body, where the Kenyon cell fibers bifurcate to project to the vertical and medial lobes.[ FlyBase:FBrf0224194 ]
Also Known As "heel" ; "knee" ; "lobe junction" (for all, see Synonyms field below)
Comment Considering that the Kenyon cell fiber projecting from the calyx divide rather than meet at this point, the term 'pedunculus junction' is somewhat misleading. Similarly, to prevent ambiguity, the terms 'heel' and 'knee' have been avoided as they are also used for referring to the mushroom body spur.
