I've gathered from a number of sources (e.g., Patel (2015), Wikipedia, and here) that the sympathetic nerves leaving the sympathetic trunk to innervate the heart and lungs are called "cardiopulmonary splanchnic nerves".
However, I've noticed that both the 14th and 15th edition of Tortora & Derrickson's A&P textbook seem to suggest that these nerves are simply called "sympathetic nerves," even though they make reference to abdominopelvic and adrenal splanchnic nerves more specifically. See below from Tortora & Derrickson (2013):
...Then, the axons of the postganglionic neurons leave the trunk by forming sympathetic nerves that extend to visceral effectors in the thoracic cavity (Figure 15.4). Sympathetic nerves provide sympathetic innervation to the heart and lungs.
Here are subsets of images from Patel (2015) [LEFT] vs Tortora & Derrickson (2013) [RIGHT] (my emphasis):
My question: Are "Sympathetic nerves" the same as "cardiopulmonary splanchnic" nerves?
- Are these names interchangeable? I can't find further evidence supporting Tortora and Derrickson's usage of this phrase in such a specific manner to refer to postganglionic neurons leaving the trunk to innervate the heart and lungs. Are they acting rogue? Are they simplifying? Any insight would be appreciated.
