_____ acute pain, chronic pain has _____ protective role in preventing further tissue damage
Unlike. no.
What can trigger nociceptive pain?
Chemical, mechanical, thermal (noxious) stimuli
Nociceptors are _____ nerve fibers that detect _____ or ______ _____ stimuli.
Specialized. actual. potential. noxious.
What are the 2 types of nociceptive pain?
somatic and visceral
Somatic pain is _____, _____ pain that _____ in duration and quality (which fibers?)
Localized. sharp. varies. (Aδ fibers).
Visceral pain is _____, _____, _____ pain (which fibers?)

Neuropathic pain is caused by _____ neural activity that arises secondary to _____, _____, or _____ of the nervous system
Abnormal. disease. injury. dysfunction.
The clinical presentation of neuropathic pain _____, but patients often describe a _____ sensation.
Varies. burning.
What are the 3 types of nociceptive pain?
Central, peripheral and sympathetic mediated.
Which syndromes can be within central pain?
Poststroke Pain, Phantom Limb Pain.
Which complications can be within peripheral pain?
Diabetic Neuropathy, Postherpetic Neuralgia.
Which syndrome can be within sympathtic mediated pain?
Complex Regional Pain.
Nociceptors detect a chemical, mechanical, or thermal noxious stimulus → _____ of stimulus to an electrical signal (action potential) → C fibers and Aδ fibers carry afferent input to the _____ horn of the spinal cord → secondary nociceptive neurons in the _____ tract carry afferent input to the _____ in the CNS → pain perception and a response sent along _____ pathways, which results in pain modulation and/or a reaction
Conversion. dorsal. spinothalamic. thalamus. efferent.
When is action potential formed in the nociceptors?
When surpasses threshold of them.
Withdrawal reflex is _____ _____ reflex that causes a part of the body to move away from a painful stimulus, via _____ of flexor muscles and _____ of extensor muscles
Polysynaptic. spinal. contraction. relaxation.
What is Hyperalgesia?
Exaggerated response to painful stimuli
(increased sensitivity to painful stimuli)
What is Allodynia?
Pain from non-painful stimuli
_____ _____ pain disorders can be a significant driver to the sensitization of central nociceptive neurons, depends on _____, _____ and _____ predisposing factors of the CNS prior to and during the onset of injury.
Chronic. peripheral. psychological. biological. environmental.
