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
