receptor
Spinal nerve
Size of receptive fields increases from distal to proximal

Anterolateral system
Primary somatosensory
cortex (areas1, 2, 3a, 3b)
Slowly
adapting
spinal cord
Brain stem
Somatosensory cortex
Schwann-cell
polymodal nociceptors
unimodal nociceptors
Aδ-fibres(~15 m/sec; 1.0-1.5 μm)
mediate the first pain
C-fibres(~1 m/sec; 0.3-0.5 μm)
mediate the second pain
Nociceptors possess a high activation threshold
