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.
Rods and cones in retina: colourized 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.
Your Guide to Eye Disease Prevention... The following describes important vision nutrients - food for the eyes - the foods they are found in, conditions for which their use is relevant, and their sources in supplements.
Retina close up cross section | The retina is the innermost layer of the eye and is composed of several layers of neurons interconnected by synapses. The only neurons that are directly sensitive to light are the photoreceptor cells, rods and cones. Light energy creates an image of the visual world on the retina, triggering nerve impulses that are sent to the visual centers of the brain through the optic nerve.
