Light goes through lens, which refracts light to retina. In low light tampetum reflects more light to retina. Rods use rhodopsin for light absorption; cones use photopsin for color absorption. Creates neurotransmission through chemical reaction from rhodopsin and photopsin to optic nerve.
The puppy’s body reflects and scatters the light waves into our eyes. In a sense, information about the puppy has been encoded into visible light waves. The optical elements of the eye focus the encoded light waves onto our retina as a map of bright and dim colored dots, known as the retinal image.
Basic Anatomy and Physiology of the Eye Abstract This chapter describes the anatomy of the eyeball, the visual pathway, and the ocular adnexae. It also provides a basic introduction to the physiology and functioning of the eye. Introduction The eye is the primary organ of vision. Each
Basic Structure of the Eye and Supporting Structures. The Globe. The eye has three layers or coats, three com-partments and contains three fluids (Figure 2.2). 1. The three coats of the eye are as follows: Outer fibrous layer: cornea. sclera. lamina cribrosa. Middle vascular layer (“uveal tract”): iris.
