Chapter 43, Problem 5TYU
Summary Introduction
Introduction: The human eye is a visual organ, having the ability to receive and process visual information. The eye detects light and converts it into electro-chemical impulses which are transmitted to the brain through optic nerves that result in the formation of an image on the retina which is a part of an eye. The human eye consists of iris which regulates the size of pupil, lens, cornea, ciliary muscles, and retina, where the image formation takes place.

How do thosecells work?arrow_forwardThe transduction process of converting light into neural signals sent to the central nervous system involves which of these steps? A. Bipolar Cells collect signals from Rods and Cones. B. The Optic Nerve carries signals about light from the Lateral Geniculate Nuclues to the Retinal Ganglion Cells. C. Retinal Ganglion Cells relay information to Rods and Cones. D. Light that reaches the eyes passes first through the Retina which focuses that light onto the Cornea.arrow_forwardEven though they are located in the back of the retinal tissue, what is the importance of the rod and cone photoreceptor cells to our sense of sight?arrow_forward
