Question
Chapter 38, Problem 11TYU
Summary Introduction
To determine:
The difference by comparing a bloodhound and a human, if bloodhounds, which are adept at following a scent trail even days old, have 1,000 times as many olfactory receptor cells as humans have. Give reason, this difference contribute to the tracking ability of these dogs.
Introduction:
The bloodhound has very keen senses which they used to find the missing peoples and prisoners. The bred of bloodhound is very large and senses are sharp, far stronger than humans.

- Include a 5-10 sentence explanation of how the sheep’s eye senses light and relays that data to the brain to interpret visual information. Some pieces to consider: What path does the light travel? What structures and pigments does it interact with? How does the signal travel to the brain? Where in the brain is the data processed? How is this different in the high light vs low light? How might the sheep’s vision differ from our own?arrow_forwardThe sensory systems are complex and have the amazing ability to respond to different types of environmental stimuli.

B the individual receptive fields that accomplish a 2.5 D sketch. C the problem of how the visual system extracts information about the three-dimensional structure of an object from a flat retinal image.arrow_forwardWhich sensory processing principle listed below best explains why we detect heat sensation when eating foods that contain capsaicin, the molecule found in chili peppers. a. Parallel processing. b. Labeled lines. c. Topographic maps. d. Efferent modulation . e. Neural plasticity.arrow_forwardWatch this video (http://openstaxcollege.org/l/occipital) to learn more about a transverse section through the brain that depicts the visual pathway from the eye to the occipital cortex. The first half of the pathway is the projection from the RGCs through the optic nerve to the lateral geniculate nucleus in the thalamus on either side. This first fiber in the pathway synapses on a thalamic cell that then projects to the visual cortex in the occipital lobe where seeing, or visual perception, takes place. This video gives an abbreviated overview of the visual system by concentrating on the pathway from the eyes to the occipital lobe. The video makes the statement (at 0:45) that specialized cells in the retina called ganglion cells convert the light rays into electrical signals. What aspect of retinal processing is simplified by that statement? Explain your answer.arrow_forward
- Watch this video (http://openstaxcollege.org/l/DanielleReed) to learn about Dr. Danielle Reed of the Monell Chemical Senses Center in Philadelphia, PA, who became interested in science at an early age because of her sensory experiences. She recognized that her sense of taste was unique compared with other people she knew. Now, she studies the genetic differences between people and their sensitivities to taste stimuli. In the video, there is a brief image of a person sticking out their tongue, which has been covered with a colored dye. This is how Dr. Reed is able to visualize and count papillae on the surface of the tongue. People fall into two large groups known as tasters and non-tasters on the basis of the density of papillae on their tongue, which also indicates the number of taste buds. Non-tasters can taste food, but they are not as sensitive to certain tastes, such as bitterness. Dr. Reed discovered that she is a non-taster, which explains why she perceived bitterness differently than other people she knew. Are you very sensitive to tastes? Can you see any similarities among the members of your family?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. Specific wavelengths of sound cause specific regions of the basilar membrane to vibrate, much like the keys of a piano produce sound at different frequencies. Based on the animation, where do frequencies–from high to low pitches–cause activity in the hair cells within the cochlear duct?arrow_forwardWatch this video (http://openstaxcollege.org/l/ear1) to learn more about how the structures of the ear convert sound waves into a neural signal by moving the hairs, or stereocilia, of the cochlear duct. Specific locations along the length of the duct encode specific frequencies, or pitches. The brain interprets the meaning of the sounds we hear as music, speech, noise, etc. Which ear structures are responsible for the amplification and transfer of sound from the external ear to the inner ear?arrow_forward
- Many people believe that blind people have supernatural hearing. How would brain plasticity explain how enhanced hearing might result from greater reliance on hearing or from just using auditory information more effectively?arrow_forwardIn humans, what happens to visual information from the left visual field?A. It reaches the right half of each retina, which sends messages to the left hemisphere.B. It reaches the right half of each retina, which sends messages to the right hemisphere.C. It reaches the left half of each retina, which sends messages to the left hemisphere.D. It reaches the left half of each retina, which sends messages to the right hemisphere.arrow_forwardWhat do the sensory systems of annelids, mollusks, arthropods, and vertebrates have in common?a.
