Nerve Cardiac Cervical Lower

Lower cervical cardiac nerve (lat. nervus cardiacus cervicalis minor, PNA, BNA, JNA) is a paired nerve, which is a branch of the vagus nerve. It passes through the lower part of the neck, where it joins the brachial plexus and forms the superficial cervical branch.

The superior cervical cardiac nerve is located in the upper part of the neck and is a branch of the superior vagus nerve, which exits the spinal cord at the level of the first two thoracic vertebrae. The nerve passes through the foramen in the transverse processes of the cervical vertebrae and enters the chest cavity, where it divides into two trunks: the superior and inferior cardiac nerves.

The inferior cardiac nerve is a branch of the inferior vagus nerve and passes through the back of the chest and abdomen. It innervates the diaphragm, the muscles of the abdominal wall, the internal organs of the abdominal cavity and the heart.

In pathology, the nerve can be damaged or compressed as a result of injury, tumors, inflammatory processes or other diseases. In this case, various disturbances in the functioning of internal organs, including the heart, may occur.

Treatment for damage to the cardiac lower cervical nerve may include surgery, physical therapy, massage, physical therapy and other methods. In some cases, drug therapy may also be required to improve blood circulation and tissue nutrition.

In general, the inferior cervical cardiac nerve plays an important role in regulating the functioning of the heart and other internal organs. Therefore, it is necessary to monitor his condition and, if necessary, consult a doctor for diagnosis and treatment of possible pathologies.

Nerves of the neck: CARDIAC CERVICAL NERVE LOWER

The inferior cervical cardiac nerve (lat. n. cardiacus - cardiac, lat. cervicalis - cervical, and lat. inferior - lower) is the sixth paired nerve in the upper cervical plexus, C6. The roots of this nerve emerge from the spinal cord at the level of the sixth thoracic segment, where they unite to form the inferior trunk, the communicating nerve, and ultimately form the right and left root brachiocephalic nerves. These nerves later connect with sympathetic fibers to the heart.

Anatomy and function

The roots of the cardiac nerve are the lower cervical and the thoracic nerves emerge from the lateral edges of the cervical vertebrae at C2-T3. The petrosal nerves are partially lost posterior to the thoracic vertebrae, where they are crossed by the sympathetic plexuses and connected to the innervation of the heart. These commissural rows then run along the anterior surface of the levator scapulae muscle and enter the middle of the scapula. The upper points of the processes form the anterior cardiac apex, and the lower points define the posterior cardiac apex.

Nerve cells of the cardiac cervical inferior nerve generally carry functional connections and are associated with the circulatory control center in the brain, hearts, lungs, liver and kidneys. This allows nerve cells to exchange information and regulate blood circulation and cellular metabolism in the body. Some of the functions that the inferior cardiac cervical nerves perform include regulating blood pressure, heart and respiratory rates, and level regulation.
