WebPhrenic Nerve. The phrenic nerve plays a key role in breathing or respiration. It causes your diaphragm to contract and expand, giving your lungs ability to inhale and exhale air. Nerve damage can cause a paralyzed diaphragm. You may feel short of breath and have problems sleeping. An irritated phrenic nerve can cause persistent hiccups. WebThe phrenic nerve is a crucial nerve that supplies motor fibers to the diaphragm, the primary muscle responsible for breathing. If there is severe damage to the phrenic nerve, it can lead to paralysis or weakness of the diaphragm, which can have a significant impact on the volumes and capacities of the respiratory system.
