photoreceptor layer of retina

Preferred Label : photoreceptor layer of retina;

Uberon definition : The layer within the retina where the photoreceptor cell receptor segments reside.;

Uberon synonym : retinal photoreceptor layer; stratum segmentorum externorum et internorum (retina); retina photoreceptor layer;

Uberon related term : layer of rods and cones; retinal photoreceptor layers;

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. (...) The outer layer of the optic cup becomes the pigment layer of the retina, whereas the inner layer differentiates into the photoreceptive cells and neuronal layers of the retina.[well established][VHOG];
