Antworten
-
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.

-
along the spinal meninges and terminating in the left parietal somatosensory cortex
-
through the spinal column and into the right frontal motor cortex

-
pulsating neural impulses called pain spindles
-
opponent process receptors in the area surrounding the injury
-
thicker, myelinated neurons called A-delta fibres

Frage 6
Frage
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?
Antworten
-
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
Frage 7
Frage
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?
Antworten
-
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
Frage 8
Frage
Which of the following accurately describes the role of culture for pain perception?
Antworten
-
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.
