Answer
-
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.
Question 2
Question
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?
Answer
-
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
Question 3
Question
Which pain pathway transmits information about an injury that has just occurred?
Answer
-
fast
-
geniculate
-
slow
-
medial
Question 4
Question
Which pathway for pain results in the experience of pain being less localized and longer lasting?
Answer
-
endorphin
-
generic
-
slow
-
thalamic
Question 5
Question
What structures do neural transmission in the slow pain pathway depend on?
Answer
-
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
Question 6
Question
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?
Answer
-
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
Question 7
Question
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?
Answer
-
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
Question 8
Question
Which of the following accurately describes the role of culture for pain perception?
Answer
-
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.
Question 9
Question
Which theory can account for the fact that people suffering from pain sometimes report pain relief from a sugar pill placebo?
Answer
-
cognitive control
-
sensory adaptation
-
perceptual constancy
-
gate control
Question 10
Question
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?
Answer
-
overactive thyroid response
-
hypnotic induction control theory of pain
-
sympathetic nervous system control mechanisms
-
gate-control theory of pain
