A noxious stimulus is a stimulus strong enough to threaten the body's integrity (i.e. cause damage to tissue). Noxious stimulation induces peripheral afferents responsible for transducing pain (including A-delta and C-nerve fibers, as well as free nerve endings) throughout the nervous system of an organism.
Sep 1, 1996 · 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.
May 1, 2023 · This article will consider the categories of acute and nociceptive pain together. Acute noxious stimuli (e.g., heat, cold, mechanical force, or chemical stimulation) trigger nociceptors.
Sep 26, 2022 · Nociception refers to the central nervous system (CNS) and peripheral nervous system (PNS) processing of noxious stimuli, such as tissue injury and temperature extremes, which activate nociceptors and their pathways.
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.
In physiology, nociception (/ˌnəʊsɪˈsɛpʃ(ə)n/), also nocioception; from Latin nocere 'to harm/hurt') is the sensory nervous system's process of encoding noxious stimuli. It deals with a series of events and processes required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize ...
May 1, 2023 · Nociception provides a means of neural feedback that allows the central nervous system (CNS) to detect and avoid noxious and potentially damaging stimuli in both active and passive settings. The sensation of pain divides into four large types: acute pain, nociceptive pain, chronic pain, and neuropathic pain.
Dec 12, 2017 · Noxious stimuli are defined as those that can or do cause tissue damage such as high mechanical pressure, extremes of temperature (<10°C and >40°C in mammals), and chemicals such as acids.
Noxious stimuli are stimuli that elicit tissue damage and activate nociceptors. Nociceptors are sensory receptors that detect signals from damaged tissue or the threat of damage and indirectly also respond to chemicals released from the damaged tissue.
Nociception is the physiological response to noxious stimuli; Pain is an experience and therefore a highly processed response; Pain is, especially in acute pain, commonly a response to nociception: blocking nociception (for example with a nerve block) can block pain; Pain is possible without nociception (most commonly in chronic pain syndromes)
