  1. Afferent fibers
    Meaning toward the center, referring to nerves that carry nerve impulses toward the central nervous system.
  2. Analgesic
    Relief from pain
  3. Bradykinin
    Chemical mediator released during inflammation causing vasodilation.
  4. Cordotomy
    A surgical procedure that disables selected pain-conducting tracts in the spinal cord, in order to achieve loss of pain and temperature perception.
  5. Dermatome
    Area of the skin from where nerve impulses are conducted.
  6. Efferent
    Away from center, referring to nerve impulses that are conducted from the CNS to the muscles.
  7. Endogenous
    Substances are those that originate from within an organism, tissue, or cell.
  8. Histamine
    Chemical released from mast cells and basophils during immune reactions, causes vasodilation and bronchoconstriction.
  9. Intractable
    Resistant to treatment, pain that cannot be relieved by drugs.
  10. Ischemia
    Decreased blood supply to an organ or tissue.
  11. Neurotransmitter
    Neurotransmitters are endogenous chemicals that transmit signals from a neuron to a target cell across a synapse.
  12. Nociceptors
    Receptors for pain stimuli.
  13. Opiods
    Opiate-like chemicals that are released to block pain signals to the brain.
  14. Parenterrally
    Drugs administered by injection.
  15. Prostaglandin
    A group of chemical substances in the body that can exert a variety of effects, such as vasodilation, muscle contraction, and inflammation.
  16. Reticular Activating System (RAS)
    Formation in the pons and medulla that influences the brain's awareness of the incoming pain stimuli.
  17. Reticular formation
    Region in the brainstem that is involved in multiple tasks such as regulating the sleep-wake cycle and filtering incoming stimuli to discriminate irrelevant background stimuli.
  18. Rhizotomy
    A neurosurgical procedure that selectively destroys problematic nerve roots in the spinal cord.
  19. Sedative
    A substance that induces sedation by reducing irritability or excitement.
  20. Substance P
    A substance that functions as a neurotransmitter and as a neuromodulator.
  21. Tachycardia
    High heart rate
