Question 2
Which fiber type is associated with fast pain?
- Aδ fibers
- C fibers
- Aβ fibers
- TRP ion channels
Question 3
Which statement best describes slow pain?
- It involves C fibers, is much less localized, and has a larger affective component.
- It involves Aδ fibers, is well localized, and has a minor affective component.
- It involves C fibers and is well localized.

Question 4
Thermoreceptors in the anterolateral pathway are TRP ion channels that are entirely specific for temperature.
- True
- False
Question 5
Analgesics and narcotics alter pain thresholds.
- True
- False
Question 6
For its submodalities, the anterolateral pathway innervates which region?
- The entire body except the head
- Only the head
- The entire body including the head
- Only the limbs and trunk
Question 7
What type of receptors do first-order sensory neurons of the anterolateral pathway use to recognize its submodalities?
- Free nerve endings
- Encapsulated corpuscles
- Muscle spindles
- Hair follicle receptors
Question 8
Touch carried by the anterolateral pathway is described as:

- Highly discriminative and superior to the DCML pathway
- Identical to touch in the DCML pathway
- Absent
Question 9
Pain is a complex perceptual experience that includes a quantifiable sensory event called nociception and what other component?
- An affective component
- A motor component
- A thermoregulatory component
- A tactile component

Thermally evoked pain is usually felt at temperatures above 45°C or below ___°C.
Fill in the blank
Question 14
Thermoreceptors that detect skin warming are mainly which type of fibers?
- C fibers

Question 15
What happens to heat thermoreceptors during a cold event and after the cold stimulus is released?
- They shut off during the cold event and turn back on when the cold stimulus is released.
- They increase firing during the cold event and decrease firing when it ends.
- They shut off only after the cold event ends.
- They are unaffected by cold events.
Question 16
During a cold event, heat thermoreceptors ______, and they turn back on when the cold stimulus is released.
