    Study Notes

    Visceral Pain

    • Diffuse, poorly localized pain that is often referred to somatic sites, such as muscles and skin
    • Characterized by strong emotional and autonomic reactions
    • Can be activated without tissue damage
    • Afferent terminals are located in laminae I, II, V, and X
    • Afferents disperse over several segments and travel with sympathetic afferents via hypogastric, lumbar, and splanchnic nerves, as well as spinal afferents
    • Easily sensitized, making it prone to hypersensitivity

    Somatic Pain

    • Characterized by distinct localization, allowing for precise identification of the pain source
    • Pain is not referred to other areas of the body
    • Emotional responses are less intense compared to visceral pain
    • Typically associated with acute tissue damage or injury
    • Afferent terminals are located in laminae I and II
    • Afferents travel with somatic/peripheral nerves, resulting in less dispersal between segments
    • Less easily sensitized, making it less prone to hypersensitivity
