Question 1

What characteristic of fast nerve fibers permits them to transmit signals perceived as sharp, immediate pain?
A) They are nonmyelinated axons,which transmit signals faster than myelinated axons.
B) They tell your brain where your body is in space,so they allow you to perceive immediate pain.
C) They are myelinated axons,which transmit signals faster than nonmyelinated axons.
D) They respond to continued vibration and fast pressure,so they transmit pain more easily.

Accepted Answer

Fast nerve fibers, specifically A-delta fibers, are myelinated, which allows for rapid signal transmission. This myelination is what enables the perception of sharp, immediate pain, as opposed to the slower, duller pain transmitted by nonmyelinated C fibers.

Question 2

Which would be the worst tip for someone who is experiencing pain after a surgery?
A) "Distract yourself by watching interesting movies."
B) "Invite some friends over for a good discussion."
C) "Keep yourself occupied."
D) "Focus on the pain and its sensations."

Accepted Answer

Focusing on the pain and its sensations can increase the perception of pain and make it feel worse, contrary to strategies aimed at distraction or engagement in other activities which can help manage pain better.

Question 3

Why does a dog sniff virtually everything that it encounters?
A) because its sense of vision is very poor
B) because olfactory information is rarely transmitted to its brain
C) because the main way that a dog perceives the world is through olfaction
D) because sniffing is associated with pleasant odors

Accepted Answer

Dogs primarily perceive the world through their sense of smell, which is why they sniff everything they encounter. This behavior allows them to gather information about their environment.

Question 4

Which of the following has been shown to help people manage pain?
A) distraction
B) complaining
C) focusing on the pain
D) crying

Accepted Answer

Distraction has been shown to be an effective method for managing pain. It works by diverting the person's attention away from the pain, thereby reducing their perception of it.

Question 5

If you have a knee injury,you are likely to experience the most pain
A) when watching an entertaining movie.
B) right before you fall asleep.
C) when trying to focus on a math problem.
D) during a lunch date with several friends.

Accepted Answer

Pain from a knee injury is likely to be most noticeable when you are trying to fall asleep because distractions are minimal, allowing you to become more aware of the pain.

Question 6

Water splashed on your skin provides ________ stimulation.
A) tactile
B) gustatory
C) vestibular
D) olfactory

Accepted Answer

Tactile stimulation refers to sensations related to touch, which is the type of stimulation experienced when water splashes on your skin.

Question 7

To ________;the later,throbbing pain was due to ________.
A) slow fibers;fast fibers
B) fast fibers;slow fibers
C) pain receptors;pressure receptors
D) pressure receptors;pain receptors

Accepted Answer

The sharp, immediate pain was due to fast fibers, which quickly transmit pain signals for acute pain. The later, throbbing pain was due to slow fibers, which are responsible for chronic, dull, and aching pain sensations.

Question 8

During sensation and perception,sensory receptors on the skin transduce information and then send this information to
A) pain receptors.
B) pressure receptors.
C) the somatosensory cortex.
D) the hippocampus.

Accepted Answer

The somatosensory cortex is the part of the brain responsible for processing sensory information from the skin, such as touch, temperature, and pain.

Question 10

When Margot was a child,her mother baked bread on Fridays.As an adult,whenever Margot smells bread baking she remembers her mother and feels happy.The mood and memories
Result from the processing of smell information in the
A) thalamus.
B) olfactory epithelium.
C) olfactory bulb.
D) amygdala.

Accepted Answer

The amygdala is a brain structure that is involved in processing emotions, including those associated with memories. The olfactory bulb is responsible for transmitting olfactory information to the brain, while the thalamus is responsible for relaying sensory information to the cerebral cortex. The olfactory epithelium is the tissue that lines the nasal cavity and contains the receptors that detect odors.

Question 11

There are several steps involved in a person being able to feel a touch on his or her skin and experience it as pleasurable.Which of the following displays these steps in the correct order?
A) (1) sensation,(2),tactile stimulation,(3) transduction,(4) perception
B) (1) tactile stimulation,(2) perception,(3) transduction,(4) sensation
C) (1) perception,(2) tactile stimulation,(3) transduction,(4) sensation
D) (1) tactile stimulation,(2) sensation,(3) transduction,(4) perception

Accepted Answer

The correct sequence for feeling a touch on the skin and experiencing it as pleasurable starts with tactile stimulation (the physical touch), followed by sensation (the body's initial response to the stimulus), then transduction (the conversion of the touch into neural signals), and finally perception (the brain's interpretation of these signals as pleasurable).

Question 12

Temperature receptors that signify intense heat when they are activated
A) also signify cold when they are inhibited.
B) generally signify cold when they are inactive.
C) oppose the activity of receptors signifying cold.
D) may respond simultaneously with receptors signifying cold.

Accepted Answer

Temperature receptors can respond to a range of temperatures, and it is possible for receptors that signify intense heat to be activated simultaneously with those that signify cold, especially in complex temperature environments.

Question 13

Which of the following detects temperature and then sends information about temperature to the brain?
A) warm and cold receptors
B) fast and slow fibers
C) cranial and spinal nerves
D) kinesthetic and vestibular senses

Accepted Answer

Warm and cold receptors are specialized sensory receptors in the skin that detect temperature changes and send this information to the brain for interpretation, allowing us to perceive warmth and coldness.

Question 14

Regarding smell,which of the following statements is generally the most accurate?
A) People are better at discriminating among odors than they are at identifying them;
Men generally outperform women.
B) People are better at discriminating among odors than they are at identifying them;women generally outperform men.
C) People are better at identifying odors than they are at discriminating among them;
Men generally outperform women.
D) People are better at identifying odors than they are at discriminating among them;women generally outperform men.

Accepted Answer

Research shows that people are generally better at discriminating among odors (noticing differences between them) than they are at accurately identifying what those odors are. Additionally, studies have found that women tend to outperform men in tasks related to both identifying and discriminating among odors.

Question 15

A) strong reliance on olfaction to determine which foods were poisonous.
B) inability to detect pleasant odors.
C) reliance on vision as the main way of perceiving the world.
D) inability to transmit olfactory information to the brain.

Accepted Answer

Humans have evolved to rely more on vision than on smell, which has led to a less developed sense of smell compared to species like dogs that depend more heavily on olfaction for survival tasks such as finding food or detecting predators.

Question 18

The sense that allows you to determine the location of your body and limbs in space is called
A) gustation.
B) olfactory.
C) kinesthetic.
D) vestibular.

Accepted Answer
