A 32 year old man visits his physician and is diagnosed with a herniated disc impinging the spinal nerve that exits inferior to the C6 veebra. Pain from the impinged nerve would most likely radiate to which cutaneous region?
Correct Answer: Lateral surface of digit 5
Description: The C7 spinal nerve exits inferior to the C6 veebra. The C7 dermatome is associated with digit 5, and therefore, pain would radiate to the lateral surface of digit 5.Ref: Greenberg D.A., Aminoff M.J., Simon R.P. (2012). Chapter 9. Motor Disorders.
