Iodopsin;found in membranes of outer segment 1 of 12 When will iodopsin produce a generator potential? In bright light 2 of 12 What type of vision do cones produce? Colour vision 3 of 12 What are the 3 different forms of iodopsin? Blue/Green/Red 4 of 12 What is the theory called in relation to this? The trichromatic theory of colour vision 5 of 12 What determines colour vision? The degree of stimulation of each type of cone 6 of 12 Where are rods and cones found in the eye? In a layer inside the choroid 7 of 12 What is the name for the sensory cells beyond the layer of bipolar neurones? Ganglion cells 8 of 12 What makes up the optic nerve and function of optic nerve ? The axons of the ganglion cells that group together -carries impulses from the retina to the brain 9 of 12 What is meant by high visual acuity? Ability of the cones to provide colour vision of high resolution; enabling the brain to distinguish between 2 points that are very close together 10 of 12 What is binocular /stereoscopic vision? Allows accurate judgement of distance &the ability to form a 3D image 11 of 12 Why would rabbits have their eyes positioned on the side of their heads rather than at the front? -Wider field of view -Detection of potential predators 12 of 12
