sounds. Which of the following best explains this to your friend?
O The inner ear is equiped with different sensory cells that get "excited" for each volume of sound
disturbace.
O Louder sounds cause larger action potentials than do softer sounds.
Louder sounds cause smaller action potentials than do softer sounds.
O Louder sounds induce a lower frequency of action potentials than do softer sounds.
O Louder sounds induce a higher frequency of action potentials than do softer sounds.

- Watch 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_forwardWatch 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_forwardHow is our sense of smell linked with the sense of taste?arrow_forward
