WebThe ulnar fovea sign is a clinical test used to specify the cause of ulnar-sided wrist pain. A positive ulnar fovea sign test is indicative of foveal disruption of the distal radioulnar ligaments and ulnotriquetral ligament injuries. The test is sensitive and examines the presence (or absence if negative) of ulnar fovea disruption. WebCurrent understanding is that the 6 to 7 million cones can be divided into "red" cones (64%), "green" cones (32%), and "blue" cones (2%) based on measured response curves. They provide the eye's color sensitivity. The green and red cones are concentrated in the fovea centralis . The "blue" cones have the highest sensitivity and are mostly found ...

Between species, foveae differ morphologically in the depth and width of the foveal pit and the steepness of the foveal walls, which could influence visual perception.
