pain

Question 1

According to functional neuroanatomy, pain could be classified into:

Transient pain and acute pain
Epicritic pain and protopathic pain
Nociceptive and and neurogenic
Central and peripheral pain
Somatic and visceral pain

Answer 1

Nociceptive and and neurogenic

Question 2

Regarding the pathophysiology of 1/1 pain, one statement is true:

1.Convergence of deep and cutaneous afferents on same dorsal horn explains the phenomenon of referred pain
2.Central sensitization is a decrease in the excitability of neurons within the CNS
3.Peripheral sensitization is an elevation in the threshold and reduction in responsiveness of peripheral nociceptors
4.Endorphins are exogenous peptides
5.Opiates suppress pain impulses by acting on neurons of the ventral horn of spinal cord

Answer 2

Convergence of deep and cutaneous afferents on same dorsal horn explains the phenomenon of referred pain

Question 3

Regarding treatment of chronic pain, one statement is true:

1.Invasive procedures include heat & cold application
2.Sympathetic blockade is one method of counterstimulation
3.TENS is one of the psychological methods
4.Neurolysis is highly recommended for the time being
5.Counterstimulation is less likely to be effective if there is significant deafferentation

Answer 3

Counterstimulation is less likely to be effective if there is significant deafferentation
