Pain |
An unpleasant sensory and emotional experience associated with actual orpotential tissue damage. |
|
Suffering |
An unpleasant emotional state that is not outwardly represented originating from either a physical or physiological source. |
|
Distress |
The external expression by behavior or emotion of suffering that an observer can see. |
|
Algology |
The science and study of pain. |
|
Allodynia |
Pain caused by a stimulus that does not normally provoke pain. |
|
Analgesia |
Absence of pain in the presence of a stimulus that would normally be painful. |
|
Analgesic |
Drugs that induce analgesia. |
|
Anesthesia
|
The absence of all sensory modalities, can be local, regional, or total. |
|
Anesthetics |
Drugs that induce regional or general anesthesia |
|
Casualgia |
Syndrome of prolonged burning pain, allodynia, and hyperpathia after a traumatic nerve lesion, often combined with vasomotor and sudomotor dysfunction and later trophic changes. |
|
Central Pain |
Pain associated with a lesion of the CNS |
|
Deafferation Pain |
Pain caused by loss of sensory input into the CNS, as occurs with avulsion of the brachial plexus or other types of peripheral nerve lesions, or caused by pathology of the CNS |
|
Dermatome |
Sensory segmental supply to skin and subcutaneous tissue |
|
Dysethesia |
An unpleasant spontaneous or evoked abnormal sensation |
|
Hyperalgesia |
Increased response to a stimulation that is normally painful |
|
Hypoalgesia |
Diminished sensitivity to noxious stimulation |
|
Hyperesthesia |
Increased sensitivity to stimulation, excluding the special senses |
|
Hypoesthesia |
Diminished sensitivity to stimulation, excluding the special senses |
|
Neuralgia |
Pain in the distribution of a nerve or nerves |
|
Neuritis |
Inflammation of nerve cells or nerves |
|
Neuropathy |
Disturbance of function or a pathologic change in a nerve |
|
Nociception |
Reception, conduction, and CNS processing of nerve signals generated by the stimulation of nociceptors. It is the physiologic process that when carried to completion results in the conscious perception of pain |
|
Nociceptor |
Receptor preferentially sensitive to a noxious stimulus or to a stimulus that would become noxious if prolonged |
|
Nociceptor Threshold |
Minimum strength of a stimulus that will cause a nociceptor to generate an impulse |
|
Noxious Stimulus |
Stimulus that is actually or potentially damaging to tissue or isof a quality or intensity to trigger nociceptive reactions |
|
Pain Threshold |
The least experience of pain that a subject can recognize. In mostcases is higher than the nociceptor threshold. Relatively constant among speciesand individuals |
|
Pain Tolerance |
Greatest level of pain that a subject will tolerate. Varies considerably between species and individuals |
|
Pain Tolerance Range |
Difference between the pain detection threshold and the pain tolerance threshold |
|
Paresthesia |
Spontaneous or evoked abnormal sensation. Not painful, as opposedto dysethesia |
|
Radiculalgia |
Pain along the distribution of one or more sensory nerve roots |
|
Radiculopathy |
Disturbance of function or pathological change in one or morenerve roots |
|
Radiculitis |
Inflamation of one or more nerve roots |
|
Reflex |
Involuntary, purposeful, and orderly reactions to stimulus. The anatomicbasis for the reflex arc consists of a receptor, a primary afferent nerve fiberassociated with the receptor, a region of integration in the spinal cord or brainstem and a lower motor neuron leading to an effector organ (skeletal or smoothmuscle or glands) |
|
Reaction |
Combination of reflexes designed to produce a widespread movementin relation to the application of a stimulus. Reactions are mass reflexes not undervoluntary control and therefore do not involve the cerebral cortex |
|
Response |
Willful movement of the body or parts of the body that requiresinvolvement of the somatosensory cerebral cortex |
|
Somatic |
Describes input for body tissues other than viscera |
|
Somatic Pain |
General nociceptor based pain |
|
How Visceral Pain differs from Somatic Pain. |
Pain...: That cannot be evoked from all organs (such as the liver and kidneys) Is not evoked by burning and cutting That isp oorly localized That may be from nociceptors or other receptors that may have other functions |
