The phrenic nerve is primarily responsible for providing sensory innervation to the fibrous pericardium and the parietal layer of the serous pericardium, which is essential for pain perception related to pericardial conditions. Lastly, the sympathetic nerves contribute to the autonomic regulation of the heart and have a role in conveying sensations as well.
