Week 4 - Physiologic Dimensions of Pain

Question 1

What is the somatic pain found in? (4)

Answer 1

• joints
• muscles
• bone
• tissue pain

Question 2

What is visceral pain? (3)

Answer 2

• from the organs
• tumour involvement of the organ capsule causes aching and localized pain
• obstruction of hollow organs causes intermittent cramping and poorly localized pain

Question 3

What is referred pain? (3)

Answer 3

• from an organ, but felt elsewhere
• perceived in a distant area
• commonly with visceral pain

Question 4

What is neuropathic pain?

Answer 4

damage to nerve cells

Question 5

What are the 4 types of pain?

Answer 5

• somatic
• visceral
• referred
• neuropathic

Question 6

What are the 2 pain classifications?

Answer 6

• nociceptive (normal)
• Neuropathic (pathologic)

Question 7

What is nociceptive pain? (2)

Answer 7

• warms of actual and potential injury
• initiates the fight or flight autoimmune stress response

Question 8

What is somatic pain? (3)

Answer 8

• arises from nerve receptors in the skin or close to the surface (bones, muscles, joints, or connective tissue)
• sharp and well localized, or dull and diffuse
• accompanied by nausea and vomiting

Question 9

What is neuropathic pain pathology?

Answer 9

abnormal processing of the sensory input as a result of injury of the peripheral or central nervous system

Question 10

What are the 2 types of neuropathic pain?

Answer 10

Centrally generated pain and Peripherally generated pain

Question 11

What is centrally generated pain (3)

Answer 11

• deafferentation pain:
• injury to either the peripheral or CNS (ex. phantom pain)
• sympathetically maintained pain-associated with dysregulation of the ANS

Question 12

What is peripherally generated pain? (4)

Answer 12

painful polyneuropathies:
- pain is felt along the peripheral nerves (eg. diabetic neuropathy)

Painful mononeuropathies:
= associated with peripheral nerve injury (eg. nerve root compression, trigeminal neuralgia)

note it is burning, shooting pain
