As electromagnetic radiation enters the eye,it is transformed by the accessory structures of the ____ before transduction occurs.
A) cornea, lens, and rods
B) cones and rods
C) photopigments
D) cornea, lens, and pupil

Question

Quizplus · Accepted Answer

As electromagnetic radiation enters the eye, it first passes through the cornea, then the lens, and finally the pupil, which regulates the amount of light that enters. The accessory structures involved in transforming the radiation are therefore the cornea, lens, and pupil. Once the radiation reaches the photoreceptor cells of the retina, transduction occurs through the activation of photopigments in the cones and rods. Therefore, options A and B are incorrect, and option C only describes the process that occurs after the transformation by accessory structures.
