The parietal peritoneum covering the inferior surface of the diaphragm transits its sensory information via the phrenic nerve. In the case of peritonitis in the parietal peritoneum on the inferior surface of the diaphragm, pain may be referred through which of the following nerves?

Ans. D. Supraclavicular nervesThe phrenic nerve consists of contributions from spinal nerve levels C3 to 5.Therefore, when sensory information comes from the parietal peritoneum on the inferior diaphragmatic surface, it may refer through spinal nerves at the same levels.a. Supraclavicular nerve shares levels with the C3 and C4 levels.b. The greater and lesser occipital nerves both originate at the C2 level.c. Great auricular nerve root value is C2, C3
