When injuring a neck in a car accident and now having difficulty breathing which spinal nerves may be involved?

In a car accident that injures the neck and leads to difficulty breathing, the spinal nerves involved are likely those in the cervical region, particularly C3 to C5. These nerves innervate the diaphragm through the phrenic nerve, which is essential for breathing. Injury to these areas can impair respiratory function, leading to breathing difficulties.
