The major function of the phrenic nerves is to innervate the diaphragm, which is the primary muscle responsible for respiration. These nerves play a crucial role in controlling the movement of the diaphragm during breathing by sending signals from the brain to the diaphragm muscle. Dysfunction of the phrenic nerves can lead to respiratory issues and difficulty breathing.
The primary nerves involved in breathing are the phrenic nerve and the intercostal nerves. The phrenic nerve controls the diaphragm, the main muscle involved in breathing, while the intercostal nerves control the muscles between the ribs that help with the mechanics of breathing.
The abdominal muscles are primarily innervated by the lower intercostal nerves, which originate from the thoracic spinal nerves. These nerves come together to form the lower thoracic intercostal nerves and the subcostal nerve, collectively contributing to the innervation of the abdominal muscles.

The nerves that innervate the colon originate from the spinal levels T10-L2. These nerves form the superior mesenteric plexus, which supplies the colon with autonomic innervation.

The Phrenic & Intercostal nerves.
The face is not included in typical dermatome distribution because the cranial nerves innervate the face instead of spinal nerves. The cranial nerves, specifically the trigeminal nerve (CN V), provide sensory innervation to the face.

cranial nerves are nerves which arise from different parts of brain that are paired and 12 pair and 24 in number. peripheral nerves are neurons that exists out side brain and spinalcord and make up peripheral nerve system.
The nerves that innervate the colon originate from the spinal levels T10-L2. These nerves form the superior mesenteric plexus, which supplies the colon with autonomic innervation.
