Flashcards in Pain lecture 1 Deck (16):
T/F the brain has nociceptors
-The brain has NO nociceptors
What is pain?
-An unpleasant sensory and emotional experience associated with actual or potential tissue damage
What are the elements of pain?
What is the physiological process by which information on actual/potential tissue damage is conveyed to the CNS?
What are specialized ion channels on sensory nerve endings that respond to noxious stimuli?
What is pain resulting from activation of nociceptors as a result of actual or potential tissue damage and processing by the CNS?
What is a pathophysiological process, resulting from abnormal sensory processing, which does not signal actual or potential tissue damage, does not promote healing or repair, and may be considered a disease?
What is somatic pain?
-Pain associated with musculo-skeleton system and skin and is well defined
What is visceral pain?
-Pain that is associated with internal organs and associated tissues and is dull, burning, and poorly defined
What are types of nociceptive pain?
What does anesthesia do to sensations?
-Blocks all sensations
What are the basic processes in nociception?
Where does transduction occur?
-Nociceptor or nerve terminal
What is transmission?
-The action potential itself
What is modulation?
-The enhancement or diminishment of the the action potential
