Q
What is acute pain
A
<1 week nociceptive pain carrying signals to the brain
3
Q
How does nociceptive pain send signals to the brain
A
A-Beta, A Delta and C fibres along the ascending tracts to the thalamus
4
Q
Where does noceptive signal enter the brain
A
Thalamus
5
Q
What is the gate control theory
A
Pain decreased by
- Heat(Rubbing site of pain) decreases impulses along the ascending tract
- Descending pathway - Pain is modulated
6
Q
Where does the descending pain pathway arise from
A
Descending pathway- RGLC
Reriaquedectral grey and locus cereleus (Major NAd producer)
7
Q
How does the descending pathway of the gate controlled theory decrease pain
A
Modulates neurotransmitter levels at synapse
8
Q
What medications acts on the nociceptive pathway
A
NSAIDs
Opiods
Local anaesthesia
