Practice exam for BBS1004
, Question 1:
Which structure of the central nervous system makes us perceive a pain stimulus as painful?
1. Cerebral cortex
2. Thalamus
3. Hippocampus
4. Cerebellum
Question 2:
What term is used to refer to an exagereted reaction to an already painful stimulus?
1. Allodynia
2. Hyperlagesia
3. Analgesia
4. Nociception
Question 3:
Rubbing over your head after hitting a painful stimuli can have an effect on the pain perception
according to the gate control theory:
1. Adelta touch fibers activate interneurones, which inhibit pain signals
2. Abeta touch fibers inhibit interneurones, which inhibit pain signals
3. Adelta touch fibers inhibit ineterneurones, which inhibit pain signals
4. Abeta touch fibers activate interneurons, which inhibit pain signals
Question 4:
The release of the neurotransmitter in the synaptic cleft relies on an ion. Which ion is it?
1. Na+
2. Ca+
3. K+
4. Cl-
Question 5
Which event is responsible for step 1 in the graph below?
