Ch. 9 Pain Flashcards
nociception
technical name for pain, the activation of specialized nerve fibers that signal the occurrence of tissue damage
acute pain
short-term pain
chronic pain
recurring pain over a long period of time
psychogenic pain
purely psychological pain w/out physiological basis
neuropathic pain
pure nociception w/out significant psychological pain
somatic pain
physiological pain w/out specific tissue damage
transduction
process that takes place at the level of the receptors where chemical, mechanical, or thermal energy is converted in electrochemical nerve impulses
afferent fiber
sensory nerve fibers transmitting signals from the receptors to the spinal cord
ARS
modulation
the neural activity leading to the control of pain transmissions between the various parts of the brain
vital sign
5 basic measures that doctors get from patients
- temperature
- pulse
- blood pressure
- pain level
- respiration
pattern theory
idea that pain results from a combination impulses from nerve endings
- different patterns of stimulation caused different types of pain
specificity
idea that pain was a specific independent sensation such as heat or touch, w/ specialized receptors responding to specific stimuli
pain-prone personality
personality type that predisposes a person to experience persistent pain
diathesis-stress model
idea that some individuals may have physiological predispositions to certain factors such as depression, stress, or pain that interact w/ psychological factors to cause those outcomes
gate control theory
model of pain proposing that key processes in the experience of pain take place in the dorsal horn substantia gelatinosa of the spinal cord & are influenced by the brain
