A noxious stimulus is actually, or potentially, damaging to tissue and liable to cause pain, but does not invariably do so. Some noxious stimuli, particularly in the viscera, do not cause nociceptive responses. Other non-noxious stimuli may cause visceral pain or afferent discharges, comparable ...
The definition of stress, then, is: an event that causes by the body’s natural fight-or-flight response. The “stress response” is what happens when the body reacts to stressors (noxious stimuli). Over time, the mental, behavioral, and physical symptoms of the stress response can wear...
“Rectal hypersensitivity is defined as increased sensitivity to experimental stimuli applied to the gastrointestinal (GI) tract. It can arise due to a combination of either heightened sensitivity to noxious stimuli (hyperalgesia) and/or non-noxious stimuli (allodynia) due to factors such as peripheral...
from Chapter 5 / Lesson 3 41K Pain is a sensation that the body feels when it is damaged or exposed to harmful stimuli. Learn about the mechanisms of pain and nociception, the different types of noxious stimuli, the pain's pathway in the body, and other types of pain. Related...
48 The caudate nucleus and thalamus signal noxious stimuli, and decreased blood flow to these areas has been demonstrated in other chronic pain disorders. Studies of humans and of animals have noted that females have a lower pain threshold and tolerance and a higher sensitivity to various noxious...
The responses of primary sensory nerve cells in VR1-negative mice cultured in vitro to various noxious stimuli were severely impaired. Therefore, some people believe that VR1 plays a key role in the transmission of multiple types of noxious stimuli, and even believe that VR1 is essential for ...
Do snails recognize humans?Snails have very bad eyesight so they won't recognize you by sight. But, their sense of smell is quite good and they will begin to recognize how you smell. Can snails feel pain? Gastropods and mollusks show evidence of reacting to noxious stimuli. It has been ...

Differences between Pain in Self and Pain in others: what is Pain Empathy? The available evidence for shared pain representations shows that pain-related activations within the ACC and IC are systematically more posterior when noxious stimuli are applied, imagined, or suggested to Self than to othe...
Non-therapeutic circumcision refers to the surgical removal of part or all of the foreskin, in healthy males, where there is no medical condition requiring surgery. The arguments for and against this practice in children have been debated for many years,
