However, the downside is that
in disorders where the pain is chronic, pain serves
no purpose except to make the patient suffer more
An integral part of the pain
transmission mechanism is via neurons (nerve cells).
A neurone receives stimulus at one end, fires,
and transfers the signal to the next neurone.
Where 2 neurones meet, the gap in between is the
synapse, and the signal is propagated across the
gap by chemicals known as neurotransmitters. Neurotransmitters
are integral to our perception of pain, as well
for blocking it.
On the other side of the synapse,
there are receptors which these neurotransmitters
bind to, and once enough neurotransmitters have
bound, the next neurone will fire.
Only once the 'pain' signal arrives
from the nervous system to our brain do we register
