A 28-year-old man is admitted to the emergency department two hours after he was

involved in a road traffic accident. A radiograph, which can be seen in the accompanying image, reveals the right dome of the diaphragm is elevated and magnetic resonance imaging (MRI) confirms that the diaphragm remains intact and

the muscle fibers have not been damaged. The physician believes that the right phrenic nerve may have been injured which is resulting in the peripheral muscular part of the right dome of the diaphragm not being able to contract during inspiration.Which of the following statements correctly describes the motor innervation of the diaphragm from the right phrenic nerve?
