Question

The three mechanisms that produce visceral pain are ____, _____, and ______.

a) Tension, Compression, Dislocation

b) Distension, Ischemia, Inflammation

c) Fracture, Sprain, Strain

d) Abrasion, Laceration, Puncture

Answer 1

Visceral pain mechanisms include distension, ischemia, and inflammation, and may present as referred pain, where pain is felt in a location different from the affected organ.

Step-by-step explanation:

The three mechanisms that produce visceral pain are distension, ischemia, and inflammation. This type of pain can be felt in unexpected locations, a phenomenon known as referred pain. For example, irritation to the diaphragm may result in pain perceived in the shoulder or neck due to shared spinal cord pathways; this explains why a cardiac event like a heart attack can cause pain in the left shoulder or arm. Sensors in the walls of digestive organs are activated by stimuli such as distension.
