Question

A person who feels heart pain in her left arm is experiencing _______.
A) phantom pain
B) a lack of substance P
C) referred pain
D) graded stimulation

Referred pain is when pain is felt in a different part of the body than where the actual problem is located. Heart pain can often be felt in the left arm because the nerves that receive signals from the heart and the left arm converge at the same spinal cord level.
