A patient with a lack of oxygen to his heart will have pain in his chest and possibly in the shoulder, arms, or jaw. The nurse knows that the best explanation why this occurs is which one of these statements?
A) A problem exists with the sensory cortex and its ability to discriminate the location.
B) The lack of oxygen in his heart has resulted in decreased amount of oxygen to the areas experiencing the pain.
C) The sensory cortex does not have the ability to localize pain in the heart; consequently, the pain is felt elsewhere.
D) A lesion has developed in the dorsal root, which is preventing the sensation from being transmitted normally.
Sensory Cortex
A region of the cerebral cortex involved in receiving and interpreting sensory information from various parts of the body.
Oxygen
A chemical element essential for life, constituting about 21% of the Earth's atmosphere and required for the respiratory processes of most living organisms.
Dorsal Root
A cluster of sensory nerve fibers located on the dorsal side of the spinal cord, which carries sensory information to the brain.

Final Answer :
C
Explanation :
The sensory cortex is arranged in a specific pattern, forming a corresponding map of the body. Pain in the right hand is perceived at a specific spot on the map. Some organs, such as the heart, liver, and spleen, are absent from the brain map. Pain originating in these organs is referred because no felt image exists in which to have pain. Pain is felt by proxy, that is, by another body part that does have a felt image. The other responses are not correct explanations.
