Flashcards in W20-L7: Pain Deck (13):
1

What is the difference in response to noxious heat in hairy and glabrous skin?

Hairy skin: Has type II A (sharp) and C fibres (slow, burning)

Glabrous skin: Has only C fibres

2

What is the response to nociceptive pain?

Autonomic response, withdrawal reflex

3

How is inflammatory pain perceived?

Spontaneous pain that causes pain hypersensitivity

4

What is hyperalgesia?

When a sustained noxious stimulus causes other levels of the spinal cord to become sensitised so pain spreads

7

What are the two types of maladaptive pain?

Neuropathic pain and dysfunctional pain

8

What is neuropathic pain?

When there is a neural lesion, produces positive and negative symptoms

9

What is maladaptive pain?

When there is a low threshold for pain

10

What is dysfunctional pain?

When there is no neural lesion, no inflammation and only positive symptoms

11

What are the cortical areas involved in Top-down psychological modulation of pain?

Anterior cingulate, prefrontal cortex, insula
