Flashcards in T1- Pain,Temp Reg Deck (139)
"___ is an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage"
2 theories of pain
Specific and gate control theory
Which theory explains the amount of pain is related to the amount of tissue injury and accounts for many types of injuries but does not explain psychological contributions?
Which theory explains the complexities of the pain phenomenon?
Gate control theory
What is the perception of pain?
How many neurons are in the perception of pain?
Primary order, Secondary order and Third Order
Which order of neurons bare nerve endings in skin, muscle, joints, arteries, and viscera that respond to chemical, mechanical and thermal stimuli?
Which order of neurons can detect a wide range of of stimuli? A-delta fibers and Unmyelinated C polymodal fibers
What are examples of low-threshold mechanical information that can distract from injury pain?
Touch, vibration and pressure
Which neurotrasmitters excite pain?
glutamate and aspartate
Which neurotransmitters inhibit pain?
serotonin, GABA and endorphins
What is threshold depolarization from direct stimuli?
What is threshold depolarization from inflammatory mediators after tissue injury?
An example of ___ excitation is increased sensitivity due to inflammatory mediators like in sunburn.
What is the point at which a stimulus is perceived as pain?
T/f The pain threshold does not vary significantly among people or in the same person over time.
Crazy I know.. word for word off his slide
T/F Intense pain at one location may cause an decrease in the threshold in another location
It increases the threshold in another location
Duration of time or the intensity of pain that a person will endure before initiating pain responses and influenced by cultural perceptions, expectations, role behaviors and physical and mental health can be described as
Decreased with repeated pain, fatigue, anger, boredum, apprehension and sleep deprivation and generally increased by alcohol consumption, persistent use of pain medication hypnosis can be described as
Point at which stimulus is perceived as pain is called
Pain at one location may cause an increase in the threshold in another location is called
Duration or time or the intensity of pain that a person will endure before initiating pain responses is called
What are two classifications of pain?
Nociceptive pain: pain with normal tissue injury (somatic, visceral)
Non-nociceptive pain: neuropathic pain (peripheral and central)
This type of pain arises from connective tissue, muscle, bone and skin. When activated by A-delta fibers, is the pain sharp or dull? Is the pain well localized or poorly localized?
Acute somatic pain.
Since it is activated by A-delta, the pain is sharp and well-localized.
Pain activated by C-fibers is poorly localized and dull.
This type of pain is in the internal organs and abdomen, poorly localized due to lesser number of nociceptors.
Acute visceral pain.
This is pain in an area removed or distant from its point of organ. What type of pain is this?
- MI pain is described as referred pain.
This type of pain is a misinterpretation of nociceptive input. The cause of this type of pain is unknown, and is also defined as pain lasting longer than 3 months. What type of pain is this describing?
CHRONIC PAIN.. or medicaid pain.. whichever you like..:)
What are the most common types of chronic pain?
- Back pain (most common)
- Myofascial pain syndrome (injury to the muscle and fascia)
- Chronic postoperative pain
- Cancer pain
This type of pain is most often chronic, and is typically the result of trauma or disease of nerves. What type of pain?
