General Information
Term embryonic/larval optic stalk ID (Ontology) FBbt:00001931 (Fly Anatomy)
Definition Receptor axons that arise in the eye disc gain access to the developing optic lobe in the supraesophageal hemisphere in the embryonic/larval brain by way of the optic stalk connecting these two structures. The optic stalk is tube-like and provides a funnel through which not only the imaginal receptor axons reach the brain, but also the axons of Bolwig's nerve (Meinertzhagen and Hanson, 1993).[ FlyBase:FBrf0064800 ]
Also Known As "larval optic stalk"
