A-delta fibers in terms of pain
transmit info fast from peripheral cutaneous structures
Pain Signal: sharp and localized
C fibers in terms of pain
transmit info slow from organs and deep structures Jts.
Pain Signal: dull, achey, and diffuse

Pain can be regulated and decreased sensation of pain.
A-delta and c fibers synapse on secondary fibers (A-alpha and A-beta) these interneurons can then be inhibitory neurons and decease the sensation of pain.
