Transduction
Conversion of one form of energy into another. In sensation, the transformation of stimulus energies (sights, sounds etc) into neural impulses our brains can interpret
Lens
Behind the pupil- focuses incoming rays into an image
Accommodation
Lens changes curvature to
Rods
Retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision, when cones don’t respond
Cones
Retinal receptor cells that are concentrated near the center of the retina and that function in daylight or well lit conditions. They detect fine details and give rise to color sensations
Iris
Color muscle surrounding the pupil- regulates amount of light entering the eye
Retina
Eyeball’s light sensitive inner surface on which the rays focus is a multilayered tissue
