kipuaistimet
Kipuaistimet, also known as nociceptors, are specialized sensory nerve endings that detect and respond to noxious stimuli, which are potentially or actually damaging to tissue. These receptors are a crucial part of the pain pathway, alerting the nervous system to harmful conditions. When stimulated, nociceptors initiate a signal that travels along nerve fibers to the spinal cord and then up to the brain, where it is interpreted as pain.
There are several types of nociceptors, each sensitive to different kinds of stimuli. Mechanical nociceptors respond
The activation threshold for nociceptors is generally higher than that for other sensory receptors. This means
