OCCTH 585 Midterm Questions And
Answers
What does pain indicate? Tissue damage, and it is a protective mechanism
What are the three types of pain? acute, chronic, persistent
What is acute pain? - sharp and immediate
- at the onset of tissue damage
What is persistent pain? - *sore achy pain*
- telling us we still have tissue damage and that we are still trying to repair and protect the tissue
What is chronic pain? - Continued expression of pain in the absence of damaged tissue
- creates dysfunction and disability
- maladaptive (serves no purpose)
What is a nocioceptor? Pain Receptor / Pain Sensor`
, OCCTH 585 Midterm Questions And
Answers
What are the types of nocioceptors? - A delta
- C-fibre
What is an A-delta fiber? - Myelinated
- Conducts at a fast rate
- detects acute onset of tissue
What type of pain does an A-delta fibre detect? ACUTE
- *"A"* Delta for *A*cute
What is a c-fibre? - unmyelinated
- conducts at a slower rate
- detects more persistent pain
What type of pain does a c-fibre predict? Persistent pain
What type of fibre predicts the sore achy pain? C-Fibre
, OCCTH 585 Midterm Questions And
Answers
What type of fibre predicts the pain at the onset of tissue damage? A-delta
What is the type of tactile nocioceptor? A-beta fibre
What is an a-beta fibre? - localizes the tissue damage and maps where the painful stimuli
is coming from
In the absence of what fibre are we now not able to localize the area of an injury? - The
absence of an a-beta fibre
What do a-beta fibres contribute to? -hyperalgesia
-allodynia
What type of neurotransmitter does the a-beta fibre release? Glutamate
A-delta fibres and C-fibres work together to produce what? First and second pain
, OCCTH 585 Midterm Questions And
Answers
What is first and second pain? - First pain occurs at the time of an injury (ex: you stub
your toe against a table and scream in pain)
- Second pain occurs for the rest of the day (ex: sore achy pain that reminds you that you stubbed
your toe)
What conducts at a faster rate? A-delta fibres or C-fibres? A-delta because they are
myelinated
What is hyperalgesia? - increased sensitivity to painful stimuli
What is allodynia? - Pain due to a stimulus that does not normally provoke pain
- Increase pain perception usually at undamaged tissue surrounding the tissue injury
- ex: when you break your ankle, tissue damage is in the bones/ligaments, but if you touch the
skin surrounding it you will receive a painful sensation even though the skin is not the source of
the injury
What type of neurotransmitter is released by free nerve endings? Substance P
