Research has shown that patients with the same basic demographics who have experienced the same event (ie, knee-replacement surgery) report differing levels of pain. Which physiologic processes are involved in a patient's perception of pain?
A) Lymph system
B) Reticular activating system
C) Neuromuscular matrix
D) Endorphins and enkephalins
Ans: B
Feedback: The involvement of the reticular formation, limbic, and reticular activating systems is responsible for the individual variations in the perception of noxious stimuli. Option A is incorrect; the limbic system, not the lymph system is involved in the perception of pain. Option C is incorrect; this is a test question put in as a distracter. Endorphins and enkephalins are not physiologic processes so option D is incorrect.
