Answer
Difficulty breathing.
Solution
-
The phrenic nerve primarily innervates the diaphragm, which is the main muscle responsible for breathing.
-
The diaphragm’s contraction and relaxation are essential for the respiratory process, allowing air to enter and exit the lungs.
-
Therefore, damage to the phrenic nerve would impair the diaphragm’s function and result in difficulty breathing.
Thus, the correct answer is:

Damage to the phrenic nerve primarily affects the diaphragm, which plays a crucial role in the respiratory process. If the nerve is compromised, it can lead to difficulty breathing, as the diaphragm may not properly contract and expand, making it harder to take deep breaths or breathe efficiently, especially during physical exertion.
In addition to breathing issues, any damage to this nerve can also lead to the phenomenon known as “paradoxical chest movement,” where the chest wall may move inward during inhalation instead of outward. This can give rise to distressing breathing patterns and further complications, highlighting the importance of the phrenic nerve in respiratory health.
