Pain SensationAka: Allodynia, Hyperpathia
- Definitions
- Allodynia
- Nonpainful stimulus results in perception of pain
- Hyperpathia
- Pain out of proportion to pain stimulus
- Allodynia
Hyperalgesia (C0020429) | |
|---|---|
| Definition (MSH) | An increased sensation to painful stimuli that may follow damage to soft tissue containing NOCICEPTORS or injury to a peripheral nerve. Hyperalgesia can occur both at the site of tissue damage (primary hyperalgesia) and in the surrounding undamaged areas (secondary hyperalgesia). (Kandel et al., Principles of Neural Science, 3d ed, p386) |
| Definition (CSP) | excessive sensitivity to painful stimuli. |

Nociception (C0234194) | |
|---|---|
| Definition (GO) | The series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal. Pain is medically defined as the physical sensation of discomfort or distress caused by injury or illness, so can hence be described as a harmful stimulus which signals current (or impending) tissue damage. Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances. [http://www.onelook.com/] |
| Definition (NCI) | The stimulus-response process involving the stimulation of peripheral pain-carrying nerve fibers (e.g., C-fibers, A-delta fibers) and the transmission of impulses along peripheral nerves of the central nervous system, where the stimulus is perceived as pain. (Taber's) |
