Pain Inhibition Flashcards
Body has three _
Pain relief systems
Each pain relief system depends on preventing nerve impulses from reaching _
Higher levels of brain
Preventing nerve impulses from reaching higher levels of Brian or, by blocking them at (2)
Spinal relays
Lower parts of brain
Two nerves join at relay stations in spine, junction of two called a _
Synapse
One nerve at spine junction carries signals from the _
Sensory nerve endings
One nerve at spine junction carries signals from the sensory nerve endings, other carries them _
Up spine to brain
Synapse like a gate, normally shut, but _ can force it open
Strong impulses
(Acute pain)
Synapse at spinal relay station junction only open to one _ at a time
Type of pathway
One synapse reaches junction and blocks out other until they have _
Died out
If location of pain rubbed vigorously, faster impulse restarts and blocks out _
Slower, chronic, impulse
3 pain relief systems are (3)
Chemical block
