stress and pain Flashcards
what are the differences between slow and fast pain?
fast is A gamma fiber, sharp/pricking, high threshold, mechano and thermoreceptor, somatic sensations, withdrawal, discriminative
slow is C fibers, dull/burning/aching, high and low threshold, emotional, qualitatively complex
how do the somatosensory, cingulate and insular cortices, and PAG participate in the processing of pain?
X
What are the defense responses produced by the PAG?

What is the peripheral sensitization in this (MIGRAINE) case?
X
What are the major characteristics of the sympathoadrenal stress response system in terms of: LC and its projections, impact on the PFC and peripheral structures?
