Flashcards in Pain lecture 1 Deck (16):
1

T/F the brain has nociceptors

False
-The brain has NO nociceptors

2

What is pain?

-An unpleasant sensory and emotional experience associated with actual or potential tissue damage

3

What are the elements of pain?

-Sensory-discriminative
-Cognitive
-Emotional/affective

4

What is the physiological process by which information on actual/potential tissue damage is conveyed to the CNS?

-Nociception

5

What are specialized ion channels on sensory nerve endings that respond to noxious stimuli?

-Nociceptors

6

What is pain resulting from activation of nociceptors as a result of actual or potential tissue damage and processing by the CNS?

-Nociceptive pain

7

What is a pathophysiological process, resulting from abnormal sensory processing, which does not signal actual or potential tissue damage, does not promote healing or repair, and may be considered a disease?

-Neuropathic/Neurogenic pain

8

What is somatic pain?

-Pain associated with musculo-skeleton system and skin and is well defined

9

What is visceral pain?

-Pain that is associated with internal organs and associated tissues and is dull, burning, and poorly defined

10

What are types of nociceptive pain?

-Somatic
-Visceral
-Inflammatory

11

What does anesthesia do to sensations?

-Blocks all sensations

12

What are the basic processes in nociception?

-Transduction
-Transmission
-Modulation
-Perception

13

Where does transduction occur?

-Nociceptor or nerve terminal

14

What is transmission?

-The action potential itself

15

What is modulation?

-The enhancement or diminishment of the the action potential

16

Where does perception occur?

-The brain via the thalamus to the cortex regions
