Chapter 4 - part 6: Our Sense of Touch: Sensory Systems in the Skin

Question 1 of 10

1

What happens to the perception of pressure if a stimulus is applied continuously to a specific spot on the skin?

Select one of the following:

  • It fades in some receptive fields, but increases in others.

  • It increases over time.

  • It gradually fades.

  • It fades only if the pressure is pulsatile.

Explanation

Question 2 of 10

1

What route is taken by nerve fibres that carry information about pressure from the surface of the skin on the left side of the body?

Select one of the following:

  • past the spinal column and into the left temporal cortex

  • along the spinal meninges and terminating in the left parietal somatosensory cortex

  • through the spinal column and into the right frontal motor cortex

  • through the spinal column and into the right parietal somatosensory cortex

Explanation

Question 3 of 10

1

Which pain pathway transmits information about an injury that has just occurred?

Select one of the following:

  • fast

  • geniculate

  • slow

  • medial

Explanation

Question 4 of 10

1

Which pathway for pain results in the experience of pain being less localized and longer lasting?

Select one of the following:

  • endorphin

  • generic

  • slow

  • thalamic

Explanation

Question 5 of 10

1

What structures do neural transmission in the slow pain pathway depend on?

Select one of the following:

  • pulsating neural impulses called pain spindles

  • opponent process receptors in the area surrounding the injury

  • thicker, myelinated neurons called A-delta fibres

  • thin, unmyelinated neurons called C fibres

Explanation

Question 6 of 10

1

Catelin has had a slow throbbing pain in her ankle since she twisted it while in-line skating last week. Where are these pain signals travelling?

Select one of the following:

  • along thin, unmyelinated C fibres

  • through periacqueductal gray neurons in the midbrain

  • along ungated endorphin pathways in the hypothalamus

  • through thick, myelinated A-delta fibres

Explanation

Question 7 of 10

1

Derek dropped a hammer on his foot and shrieked a split second later at the intense pain from a newly broken toe. How did the almost instantaneous pain signals travel?

Select one of the following:

  • along thick, myelinated A-delta fibres

  • through periacqueductal gray neurons in the midbrain

  • along thin, unmyelinated C fibres

  • through gated endorphin pathways in the hypothalamus

Explanation

Question 8 of 10

1

Which of the following accurately describes the role of culture for pain perception?

Select one of the following:

  • Race has a larger impact on pain perception than does culture.

  • Culture has no impact on pain perception or attitudes toward pain.

  • Culture affects willingness to tolerate pain, but not the process of pain perception.

  • Cultural rules dictate the amount of pain experienced, but only above a certain innate threshold.

Explanation

Question 9 of 10

1

Which theory can account for the fact that people suffering from pain sometimes report pain relief from a sugar pill placebo?

Select one of the following:

  • cognitive control

  • sensory adaptation

  • perceptual constancy

  • gate control

Explanation

Question 10 of 10

1

Which of the following helps to explain an athlete’s ability to play with a broken foot and not feel the pain until much later?

Select one of the following:

  • overactive thyroid response

  • hypnotic induction control theory of pain

  • sympathetic nervous system control mechanisms

  • gate-control theory of pain
