Nociception Flashcards
Free nerve endings are not ________ and responsive to ________.
Encapsulated, noxious stimuli
When a greater noxious stimulus is required to tigger an action potential but pain shoots directly to maximal intensity and lasts longer than normal, it is known as ________.
Hyperpathia
Pain can be suppressed by either activating the ________ or inactivating ________.
Analgesia system, pain pathways
A noxious stimulus that is more painful than expected is known as ________.
Hyperalgesia
Pain is suppressed by the ________, sending signals to inhibit pain input.
Brain
When it comes to adaptation, pain receptors adapt ________.
Little, if at all
Inactivation of pain pathways can occur via two kinds of substances. These are ________ and ________.
Exogenous opiates, endogenous opioid substances
The analgesia system suppresses pain by sending efferent signals to inhibitory complexes in the ________.
Dorsal horns
Opioid substances bind to ________ in the brain and spinal cord.
μreceptors
When a non-noxious stimulus is painful, it is known as ________.
Allodynia
Nociception is the sensing of ________.
Tissue damage
________ occurs due to a neuron being repeatedly fired and thus results in a raised resting membrane potential.
Facilitation
The downward spiral is a combination of ________, ________, and ________ and leads to maintenance and exacerbation of somatic dysfunction.
Chronic inflammation, vasoconstriction, muscle spasm
