Examples of nociceptor in the following topics:
-
- There are several types and functions of nociceptors:
- Thermal nociceptors are activated by noxious heat or cold at various temperatures.
- Mechanical nociceptors respond to excess pressure or mechanical deformation.
- These mechanical nociceptors frequently have polymodal characteristics.
- Chemical nociceptors respond to a wide variety of spices commonly used in cooking.
-
- A nociceptor is a sensory nerve cell that responds to damaging or potentially damaging stimuli by sending signals to the spinal cord and brain.
- Nociceptors can respond to excessive thermal, mechanical, or chemical stimulation and often result the generation of an involuntary motor respons—for example, pulling a hand away from a hot surface.
-
- Nociceptive pain is caused by stimulation of peripheral nerve fibers that respond only to stimuli approaching or exceeding harmful intensity (nociceptors), and may be classified according to the mode of noxious stimulation.
- Deep somatic pain is initiated by the stimulation of nociceptors in ligaments, tendons, bones, blood vessels, fasciae, and muscles, and is a dull, aching, poorly localized pain.
- Superficial pain is initiated by activation of nociceptors in the skin or other superficial tissue, and is sharp, well-defined, and clearly located.
-
-
- These channels are found predominantly in smaller sensory neurons in the dorsal root ganglion cells and are activated by higher pressures, two attributes that are characteristic of nociceptors.
-
- In the periphery, the somatosensory system detects various stimuli by sensory receptors, such as by mechanoreceptors for tactile sensation and nociceptors for pain sensation.
