Module 3 - Pain

Question 1

Unpleasant sensory and emotional sensation associated with actual and potential tissue damage

Answer 1

Pain

Pain is subjective*

Question 2

3 types of fibers

Answer 2

A
B
C

Question 3

Myelinated, fastest rate of conduction, convey pressure, touch sensation

Answer 3

Type A Fibers

Aligned with someone who has acute pain

Question 4

Myelinated, transmit information from cutaneous and subcutaneous receptors

Answer 4

Type B Fibers

Question 5

Unmyelinated, smallest diameter so slowest rate of conduction

Answer 5

Type C Fibers

Associated with chronic pain

Question 6

Three Levels of Neurons

Answer 6

First-order
Second-order
Third-order

Question 7

Detects the sensation

From the periphery to CNS

Answer 7

First-order neurons

Question 8

In the spinal cord; transmit messages to the brain

Answer 8

Second-order neurons

Question 9

In the brain; relays information from the brain to the cerebral cortex to have resulting feeling of pain

Answer 9

Third-order neurons

Question 10

• used for the rapid transmission of sensory information such as discriminative touch
• Rapidly conducting large myelinated fibers

Answer 10

Discriminative Pathway (Pain pathway)

Question 11

Provides transmission of sensory information such as pain, thermal sensations, crude touch and pressure that does not require discrete localization of signal source

Answer 11

Anterolateral Pathway:

1. Paleospinothalamic Tract
2. Neospinothalamic Tract

Question 12

Paleospinothalamic Tract:

Answer 12

• slower conducting, mostly type C fibers
• Really diffuse, dull-aching sensation: CHRONIC PAIN
• Activates the reticular activation system (controls sleep/wake cycles)
• Affects arousal, mood, attention

Question 13

Neospinothalamic Tract

Answer 13

• Faster conducting, myelinated type A fibers

- allows localization, identification of pain

Question 14

Special pain receptors detect pain (nociceptors)

Answer 14

Specificity Theory

Question 15

Sensory receptors create pain signals when stimuli are too strong

Answer 15

Pattern Theory

Question 16

Pain is carried by distinct fibers in spinal cord

Answer 16

Gate Control Theory

Question 17

The brain identifies pain

Two loops b/w thalamus and cortex and the network can create a pain sensation even when its not there

Answer 17

Neuromatrix pain

Question 18

When stimulus becomes pain

The point at which stimulus feels painful

Answer 18

Pain Threshold

Question 19

How much pain someone is willing to endure before doing something about it

Answer 19

Pain Tolerance

Question 20

Continued stimulation causes pain

Answer 20

Hyperpathia

Question 21

Spontaneous, unpleasant sensations

Answer 21

Paraesthesias

Question 22

Distortions of somesthetic sensation

Answer 22

Dysesthesia

Question 23

Reduced pain sensation

Answer 23

Hypalgesia

Question 24

Absence of pain

Answer 24

Analgesia

Question 25

Pain after non noxious stimulus

Answer 25

Allodynia

Question 26

COLDSPA

Answer 26

Character, Onset, Location, Duration, Severity, Pattern, Associated Factors

Question 27

Nonnarcotic Analgesics

Answer 27

Aspirin and other NSAIDS

Acetaminophen (tylenol)

Question 28

Blocks prostaglandin synthesis and effects on inflammatory system

Antipyretic and anti-inflam effect
Inhibition of COX enzymes

Answer 28

Aspirin and other NSAIDS

Question 29

Equal to aspirin and other NSAIDS but no anti-inflammatory response

Answer 29

Acetaminophen (tylenol)
