AbstractThis article is the first in a two-part series which explores pain and its management from a physiological perspective. Pain is a common experience which is often inadequately managed in hospital and community settings. While nurses are in a key position to contribute to successful pain management there are frequent accounts in the literature that nurses lack knowledge about pain management. Knowledge of pain physiology is fundamental to its successful management. This article introduces nurses to the components in the pain pathway and describes nociceptors which respond to pain stimuli and identifies pain fibres which carry pain information to the spinal cord. The processing of pain in the spinal cord is explained and the role of the brain in the manifestation of the pain experience is also explored. The gate control theory of pain and the more recent neuromatrix theory are discussed.
