Extra-ocular muscles that participate in the vestibular ocular reflex (VOR). These muscles are paired with the semi-circular canals of the vestibular system to allow the eyes to maintain stabilized during slow movements of the head.
We’ve all heard that sharks can smell blood in the water, but their eyes are also quite advanced. Did you know that, the great white has an eye structure almost identical to humans? Source: Smithsonian Magazine
Rods and cones in retina: colorized scanning electron micrograph (SEM) of rods and cones, showing the structure of the eye retina. Rods (green) are long nerve cells which respond to dim light, enabling images to be detected. Cones (blue) are shorter cone-like cells which detect colour. Rods and cones pass visual signals through the optic nerve to the brain. Pigment cells block light from passing further. Magnification: unknown.
For the first time, scientists at the University of Wisconsin-Madison have made early retina structures containing proliferating neuroretinal progenitor cells using induced pluripotent stem (iPS) cells derived from human blood.
