pain - complex interaction between physical, cognitive, spiritual, emotional, and environmental factors gate control theory - other sensations, such as touch, may block or close the pain gate-a distraction neuromatrix theory - brain produces patterns of nerve impulses drawn from various inputs, including genetic, psychologic, and cognitive experiences pain perception systems - sensory-discriminative, affective-motivational, cognitive-evaluative sensory-discriminative - presence, characte...

NU 545 Unit 2 Exam Questions and Answers All Correct What are the two types of fibers that transmit the nerve action potentials generated by excitation of any of the nociceptors. Pages 469-470 - Answer- Nociceptors = free nerve endings in the peripheral nervous system that responds to chemical, mechanical, and thermal stimuli; when stimulated they cause nociceptive pain. Two fibers are A-delta & C fibers ***see question 7! A-delta fibers: lightly myelinated, medium sized = faster transmissi...
