Uberon definition : the narrow, proximal portion of the optic vesicle which connects the embryonic eye
and forebrain;
Uberon related term : optic stalks;
Uberon Homology note : (...) an essentially similar sequence of events occurs during the embryonic development
of the vertebrate eye. The eye initially develops as a single median evagination of
the diencephalon that soon bifurcates to form the paired optic vesicles. As each optic
vesicle grows towards the body surface, its proximal part narrows as the optic stalk,
and its distal part invaginates to form a two-layered optic cup.[well established][VHOG];
