Significance of pain provides a low-level feedback abt the functioning of our _______ systems.
bodily
Symptoms of pain can lead one to seek ___________.
treatment
Inadequate relief from pain is the most common reasons for requests for ________ or assisted ________.
euthanasia, suicide
Social support is extremely helpful for those who are ________ experiencing pain. On the flipside, issues with social support or no social support at all can cause other issues like ___________.
currently, social pain
Use of addictive painkillers can contribute to declining ______ expectancy among poorly educated whites.
life
Degree to which pain is felt depends on:
How the pain is interpreted
Context in which the pain is experienced. Sympathetic arousal is a result of diminished pain sensitivity. Can worsen due to stress.
Cultural component to pain - members of some culture react more intensity to pain than those from other cultures.
Gender diffs: women show greater sensitivity to pain.
How to measure pain:
Verbal reports - ppl use for describing pain.
Pain questionnaires: ask abt the nature of pain & its intensity.
Methodological tools can be used to gain insights abt pain.
Address the psychological components of pain:
How much fear it causes
How much it has taken over one’s life
Negative emotions make pain worse.
Pain behaviors…
Arise from chronic pain.
Help in assessing how pain has disrupted a patient’s life
Help define the characteristics of diff kinds of pain syndromes.
Physiology of Pain:
Protective mechanism to bring tissue damage into conscious awareness
Accompanied by motivational & behavioral responses
Negative emotions exacerbate pain & vice versa
Kinds of pain perception:
Mechanical nociception
Thermal damage
Def: Mechanical nociception
Results from mechanical damage to the tissues of the body.
Def: Nociception
pain perception
Def: Thermal damage
Experience of pain due to temp exposure.
Def; Polymodal nociception
Pain that triggers chemical reactions form tissue damage.
Def: Gate-Control Theory of Pain
Developed scientific understanding of pain
Nociceptors sense injury & release chemical messengers to the spinal cord.
Includes:
A-delta fibers - small myelinated fibers
C fibers
Periductal gray
Processes in the cerebral cortex are involved in cognitive judgments abt pain.
Nonciciptors in the peripheral nerves senses the pain first and then it starts to release chemical messages thru the spine which goes directly to the reticular formulation & thalamus to the cerebral cortex.
Def: A delta fibers
Response to mechanical or thermal pain
Transmit sharp, brief pain rapidly.
Def: C fibers
Unmyelinated nerve fibers.
Involved in polymodal pain
Transmit dull, aching pain.
Def: periductal gray
Located in the midbrain, results in pain relief when stimulated.
Neurons in the periductal gray connect to the reticular formation in the medulla.
Sensations are modulated by the dorsal horn in the spinal column & by downward pathways from the brain that interprets pain
Def: Endogenous opioid peptides
natural pain suppression system of the body.
Stress-induced analgesia (SIA: phenomenon where acute stress reduces sensitivity to pain.
Important bc they are a natural pain suppression system of the body.
May also be one of the mechanisms underlying various techniques of pain control.
Def: acute pain
results from a specific injury that produces tissue damage.
Disappears when the tissue is repaired.
Short in duration, lasting for 6 months or less
Def: chronic pain
begins with an acute episode but doesn’t decrease with treatment & the passage of time.
Kinds of chronic pain:
Chronic benign pain
Recurrent acute pain
Chronic progressive pain
Def: Chronic benign pain
Persists for 6 months or longer
Relatively unresponsive to treatment
Severity of pain varies
