Phrenic nerves from brachial and cervical plexus.
The phrenic nerve arises from the cervical plexus (C3-C5) and supplies the diaphragm, which is the primary muscle involved in breathing.
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).
The nerves that control the diaphragm exit the central nervous system from the cervical spinal cord, specifically from the C3 to C5 nerve roots. These nerve roots come together to form the phrenic nerve, which is the primary nerve responsible for controlling the movement of the diaphragm during breathing.
The diaphragm is primarily stimulated to contract by the phrenic nerves, which originate from the spinal cord. The phrenic nerves send signals to the diaphragm to contract and initiate breathing. Additionally, chemical factors like excess CO2 levels in the blood can also stimulate the diaphragm to increase breathing rate.
The largest nerve in the human body is the sciatic nerve. It serves the function of connecting the spinal cord to the leg and foot muscles, allowing for movement and sensation in the lower body.

Nervous innervation to the diaphragm is from the C3-C4-C5 spinal nerve roots.
The phrenic nerve, which arises from the C3-C5 nerve roots in the cervical spine, innervates the diaphragm muscle and controls its function. Dysfunction of the phrenic nerve can impair breathing and lead to respiratory issues.
The phrenic nerve arises from the cervical plexus (C3-C5) and supplies the diaphragm, which is the primary muscle involved in breathing.
The phrenic nerve is responsible for stimulating the diaphragm to contract and initiate the process of inhalation. It arises from the spinal cord and plays a crucial role in controlling breathing by sending signals to the diaphragm muscle.

It should be the nerve to diaphragm.
Spinal Accessory 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).
