Explanation Refer to Fig. 33.16, “Eyeshine of a black-footed ferret” in the textbook. Ferret is a nocturnal carnivore that has light reflecting material in its choroid. The layer in the eye consists of tapetum lucidum that is located just behind the retina. When light enters the eye, it hits the mirror-like tapetum lucidum and reflects back leading to eyeshine effect...

Summary Introduction

To explain: The presence of light-reflecting material in eyes of nocturnal carnivores maximizes the degree to which light excites photoreceptors and also causes the perceived image to be blurred.

Introduction: Nocturnal animals refer to animals that are awake and active during the night. They have good night vision, keen senses of smell, touch, and hearing. They consist of a layer of cells tapetum lucidum behind their retina. It reflects light back through the eye. This enables them to see in dim light or dark.

In order to see a dim star at night, it is better not to look directly at it. If you see it from the “corner of your eye” and then turn to look at it, it may disappear. Explain how this occurs. Also, you can staredirectly at an object in daylight and continue seeing it, despite the bleaching of photoreceptors. Explain how this is possible.

How are Ca2+ channels involved in phototransduction? they cause neurotransmitter release even if no action potentials are produced are not affected by PDE activation in the outer segments when open, they lead to hyperpolarization in photoreceptors in darkness, they do not rely on CGMP levels The density of cones in the retina: is highest where cone outer segments increase in diameter is lowest where retinal blood vessels are absent is drastically less than that of rods in the fovea is indicative of what areas are associated with acuity The recycling of rhodopsin.

key function of rod photoreceptors is to: detect colors detect fine details in the visual field. detect light under low levels of illumination. detect light under high levels of illumination. During phototransduction, transducin activates phosphodiesterase (PDE) that converts: GTP to GDP CGMP to GMP retinal cis to retinal trans retinal trans to retinal cis
