The right phrenic nerve passes over the right atrium. The left phrenic nerve passes over the pericardium of the left ventricle and pierces the diaphragm separately. The pericardiacophrenic arteries and veins travel with their respective phrenic nerves. The phrenic nerve can be marked by a line connecting these two points:

Kehr's sign is a classic example of referred pain: irritation of the diaphragm is signaled by the phrenic nerve as pain in the area above the collarbone. This is because the supraclavicular nerves have the same cervical nerves origin as the phrenic nerve, C3, C4, and C5. [citation needed]

The axillary block is also the safest of the four main approaches to the brachial plexus, as it does not risk paresis of the phrenic nerve, nor does it have the potential to cause pneumothorax. [12] In the axilla, the nerves of the brachial plexus and the axillary artery are enclosed together in a fibrous sheath which is a continuation of the ...

Last summer Len Barchanowicz, 45, experienced sharp pangs in his neck that felt like a pinched nerve. After about a week, his symptoms intensified and he experienced chest pain and trouble ...
The subclavian nerve may issue a branch called the accessory phrenic nerve [3] [2] which innervates the diaphragm. [3] The accessory phrenic nerve may rather branch from the C4 or C6 segments or ansa cervicalis. [4] This nerve usually joins with the phrenic nerve before innervating the diaphragm, ventral to the subclavian vein. [5]
