Chapter 43, Problem 8TYU
Summary Introduction
To describe: The ability of connoisseurs to taste varieties of cheese or wine, when there are only a few types of taste receptors present.
Introduction: Chemoreceptors present in the animals are used to detect the chemical substances present in the food, water, and air. They help in evaluating the taste and smell of food. This mechanism is called chemoreception. Some animals use this property to communicate with their mate. Chemoreceptors are of two types: gustatory and olfactory.

Light sensitivitylabel the discussions with titlesDiscussion 1 – Answer in 100 – 150 WordsThere is a relationship between eye color and sensitivity to light. What is that relationship exactly and what causes some color eyes to be more sensitive than others? Discussion 2 – Answer in 100 – 150 WordsExplain the process of perception. Discussion 3 – Answer in 100 – 150 WordsDo humans actually have a “blind spot?” If so, what causes this blind spot and what are some disadvantages of it? Discussion 4 – Answer in 100 – 150 WordsThoughts? Discussion 5 – Answer in 100 – 150 WordsRefer to Figure 3.25 (b) in Ch. 3 of Sensation and Perception. Typically, the right side of the body is controlled and interpreted by the left hemisphere of the brain, and vice versa. How is this different in the visual system? Why?

- Watch this video (http://openstaxcollege.org/l/l_3-D1) to learn more about how the brain perceives 3-D motion. Similar to how retinal disparity offers 3-D moviegoers a way to extract 3-D information from the two-dimensional visual field projected onto the retina, the brain can extract information about movement in space by comparing what the two eyes see. If movement of a visual stimulus is leftward in one eye and rightward in the opposite eye, the brain interprets this as movement toward (or away) from the face along the midline. If both eyes see an object moving in the same direction, but at different rates, what would that mean for spatial movement?arrow_forwardWatch this animation (http://openstaxcollege.org/l/ear2) to learn more about the inner ear and to see the cochlea unroll, with the base at the back of the image and the apex at the front.

- 5. The sense of smell – is one of the possible ways to detect a signal from the environment in animals, including humans. It is now acknowledged that human can detect about 10000 types of smells (odors). Receptors, recciving the scent, can define molecules differed by only one carbon atom or by one functional group. The molecule of an odorous substance odorant, binds to granule- adsorbent in a mucus composite, covering the olfactory cells in the nasal cavity. Complex odorant-adsorbent interacts with cell membrane receptor. The final part of this signal transduction is the opening of CAMP-dependent Nat-channels in the olfactory cell membrane. This results in excitation of the olfactory neuron and transduction of action potential via olfactory nerve to the central nervous system. Explain the specificity of all proteins and non-protein molecules structure, which takes part in the odorant substance transduction.
