Pain: highly complex and subjective experience (self reported) that originates from the central nervous system (cns), the peripheral nervous system, or both. Nociceptors located within skin, connective, tissue, muscle and thoracic, abdominal and pelvic viscera detect painful sensations from the periphery and transmit them to cns. Can cause increase in pulse and bp. 2 types: nociceptive pain: well-localized pain caused by tissue injury and described as aching or throbbing. 2 types: somatic nociceptive pain: pain that can be superficial, derived from skin surface and subcutaneous tissues or deep, derived from joints, tendons, muscles or bones, visceral nociceptive pain: pain that originates from larger interior organs (ex. 2 types: acute pain: short-term and self-limiting pain that follows a predictable trajectory and dissipates after injury heals. Serves as self-protection purpose by warning of potential tissue damage: persistent/chronic pain: pain that is continuous for 6 months or longer and does not stop when injury heals.
