Question 3

Samantha gets into a new elevator in a large skyscraper and the doors close.She hears no noise,feels no vibration,and sees no movement,but she nevertheless knows that she is on her way up.What specific part of her ear is allowing her to know that she is ascending?

Accepted Answer

The saccule and utricle are parts of the vestibular system in the inner ear that detect changes in linear acceleration and gravity, respectively. As Samantha enters the elevator and it starts to move upwards, the saccule and/or utricle would detect this change in acceleration and send signals to her brain, allowing her to know that she is ascending. The organ of Corti is responsible for detecting auditory stimuli, while the stapes is one of the small bones in the middle ear that helps to transmit sound vibrations to the inner ear.

Question 6

Lewis had a hereditary disorder that caused his cochlear hair cells to progressively die,beginning with those nearest to the oval window and then on to the rest of the hair cells.What will be the earliest problem noticed?

Accepted Answer

The hereditary disorder affecting Lewis's cochlear hair cells causes high-frequency deafness. The hair cells responsible for detecting higher frequencies are located closer to the oval window, so they are affected first. Therefore, high-frequency hearing loss will be the earliest problem noticed.

Question 7

Hearing loss results from prolonged exposure to sound over ________

Accepted Answer

Prolonged exposure to sound at or above 85 dB can cause hearing loss.

Question 8

________ are rare types of neurons with only a single axon and a single dendrite,which process messages from the rods and cones.

Accepted Answer

The answer of ________ are rare types of neurons with...

Question 9

Mina had a throat infection; in a few days it had spread to her ear.What part of her ear would be affected first?

Accepted Answer

The middle ear is the part of the ear that is most commonly affected by infections that spread from the throat, such as in the case of Mina. This is because the middle ear is connected to the throat via the Eustachian tube, which can allow bacteria or viruses to travel from the throat into the middle ear. The external auditory canal and pinna are not usually affected by throat infections, and the inner ear is located deeper in the ear and is not directly connected to the Eustachian tube.

Question 10

Sensory receptors respond to changes in the environment called ________.

Accepted Answer

The answer of Sensory receptors respond to changes in the...

Question 11

Ned is reading his newspaper by holding it at arm's length.Sandra asks him why he isn't holding it closer.He explains that he would not be able to see the print if he held it closer.Which of the following corrective measures would be the best solution for Ned?

Accepted Answer

Ned needs a corrective measure that will help him see the print on the newspaper more clearly. Convex lenses are used to correct farsightedness, which is likely the reason Ned is holding the newspaper at arm's length. Convex lenses will help bring the print on the newspaper into focus and allow him to see it more clearly. Corneal ring segments and retinal transplants are not appropriate solutions for this issue. Concave lenses are used to correct nearsightedness, which is not the issue Ned is experiencing.

Question 12

Sensory receptors in muscles and joints that detect ________ never adapt.

Accepted Answer

The answer of Sensory receptors in muscles and joints that...

Question 13

There is a tiny muscle attached to the malleus,but if the muscle contracts,the sound will not be efficiently passed to the next structure,which is called the ________.

Accepted Answer

The incus is the correct answer because it is the middle bone in the chain of the three auditory ossicles in the middle ear. It receives vibrations from the malleus (to which it is attached) and transmits these to the stapes.

Question 14

Natasha has just been diagnosed as having a torn diaphragm.This confuses her since she knows her diaphragm is just above her abdomen while she feels the pain in her neck and upper arms.What she is experiencing is an example of ________.

Accepted Answer

Referred pain is when pain is perceived in a location other than the actual source of the pain. In this case, Natasha's torn diaphragm is causing pain to be felt in her neck and upper arms instead of the abdomen where the diaphragm is actually located.

Question 15

Question 18

Charlene loved to eat raw garlic in various dishes and couldn't understand why others didn't want to be around her because she didn't notice any strong smell.What sensory phenomenon is she demonstrating?

Accepted Answer

Charlene is demonstrating sensory adaptation, which occurs when a person becomes less sensitive to a constant sensory input over time. In this case, Charlene's sense of smell has adapted to the constant presence of garlic, so she doesn't notice the strong smell that others do.
