Pain Physiology

Reception, Propagation

QuestionAnswer
What are the 2 types of Pain Receptors? Mecanothermal, Chemosensitive Nociceptors
What triggers a Mechanothermal Nociceptor response? Intense/Severe MECHANICAL stimuli, TEMPERATURE extremes
What is an example of a Mecanothermal Nociceptor Stimulus? Pinch
What triggers a Chemosensitive Nociceptor response? Major Truama --> releases Bradykinin, Histamine, Prostaglandins from injured cells
What is an example of a Chemosensitive Nociceptor Stimulus? major Infection, Disease, severe Burns - Cell Death
Why do 3rd degree burns have less pain that 1st or 2nd degree burns? deep tissue burns damage Chemosensitive Nociceptors
Were do A-fibers come from? from Mechanothermal Nociceptors
What are 3 characteristics of A-fibers? 1. THICK well-myelinated; 2. FAST conduction velocity; 3. 1st PAIN
Describe 1st Pain. Short, Sharp, Stinging, Well-Localized
Where does 1st pain occur? propagated from SKIN only
What are 3 characteristics of C-fibers? 1. THIN poorly-myelinated; 2. SLOW conduction velocity; 3. 2nd PAIN
Describe 2nd Pain. Long-Lasting, Burning
Where does 2nd Pain occur? propagated from Skin, Deep Tissues, Organs
What is the significance of A-fibers? responds to lower levels of injury - Early Warning, take evasive action
Wat is the significance of C-fibers? incapacitating pain - prevents further injury

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
