Question | Answer |
---|---|
Found in the pain neurons of the dorsal horn | substance P - excitatory neurotransmitters |
Needed to transmit pain impulses from the periphery to higher brain centers | substance P - excitatory neurotransmitters |
Causes vasodilation and edema | substance P - excitatory neurotransmitters |
Released fro the brain stem and dorsal horn to inhibit pain transmission | serotonin - excitatory neurotransmitters |
Increase sensitivity to pain | prostaglandins - excitatory neurotransmitters |
Body's natural supply of morphinelike substances | endorphins, enkephalins, & dynorphins - inhibitory neurotransmitters |
Activated by stress and pain | endorphins, enkephalins, & dynorphins - inhibitory neurotransmitters |
Located within the brain, spinal cord, and gastrointestinal tract | endorphins, enkephalins, & dynorphins - inhibitory neurotransmitters |
Cause analgesia when they attach to opiate receptors in the brain | endorphins, enkephalins, & dynorphins - inhibitory neurotransmitters |
Released from plasma that leaks from surrounding blood vessels at the site of tissue injury | bradykinin - inhibitory neurotransmitters |
Binds to receptors on peripheral nerves, increasing pain stimuli | bradykinin - inhibitory neurotransmitters |
