Phrenic
The phrenic nerve is the motor nerve serving the diaphragm.
The diaphragm is primarily innervated by the phrenic nerve which is formed from the cervical nerves C3, C4, and C5.
Phrenic nerve supplies motor nerves to the diaphragm.

The Vagus Nerve.
The phrenic nerve innervates the diaphragm which is our main breathing muscle. It is a broad flat sheet that encircles our lower ribcage and separates our thoracic from our abdominal cavities. The phrenic nerve arises from the C3-C5 level of our vertebrae. In the event of a broken neck, that is often the determining factor whether someone will die (from an inability to breathe) or is just paralyzed.
The diaphragm is attached to the xiphoid process (Sternum), the lower six costal cartilages (ribs) and the upper three lumbar vertebrae (back bone), and the fibres converge to a central median tendon. It is supplied by the phrenic nerve.
sciatic nerve
The entire motor supply to the diaphragm arises from the anterior rami of segments C3-C5 of the spinal cord, and runs within the right and left phrenic nerves. In addition, pain and proprioception for the diaphragm also run within the phernic nerve, although not entirely. Sensory nerve supply for the diaphragm also is supplied by the intercostal nerves (arises from T5-T11) and the subcostal nerves (T12).
Auditory Nerve from brain to ear.

What are Hiccups?Hiccups are involuntary spasms of the diaphragm muscles that draw air into the lungs. Hiccups occur when the diaphragm becomes irritated, causing it to contract suddenly and involuntarily. As the diaphragm contracts, the opening between the vocal cords (glottis) snaps shut, causing the hiccup sound. Hiccups are usually caused when the nerve that extends from the neck to the chest is irritated (the phrenic and vagus nerves).
The nerve that stimulates the diaphragm to contract arises from the cervical plexus. When people have diaphragmatic pacemakers, an electrical stimulation is used to help with their breathing.
The deep thorax muscles are the deep muscles of the thorax that promotes the inspiratory phase of breathing. When breathing the diaphragm contracts, producing a negative pressure, which forces are into the lungs.
The vestibulocochlear nerve innervates the ear.
