What is a French nerve?

Frenic nerve is one of the pairs of nerves marked to the left and to the right that sends the signals between the brain to the membrane. When the membrane moves, it pulls the air and pushes it out of the lungs. Nerves receive automatic signals to keep the body breathing, but people can also apply some control over the movement of the diaphragm, allowing them to do things like holding their breath. Nerve damage worsens this ability and can sometimes cause very serious health problems.

Nerve path

Frenic nerve comes from the brain and initially travels down next to the main spinal cord, which is closed in the spine. Twin nerves immediately branches and leaves the third, 4th or 5th vertebrae in the throat. Under the muscles of the neck and shoulder bones, the true French nerve passes to the base of the right lungs, where it comes into contact with the heart and bronchial. The left nerve follows a similar path and passes through a nearby before entering the diaphragm.

membrane

the membrane is large muscles in the shape of a dome under the lungs that receive its operating signals through a frenic nerve. When you breathe, it is closed to give the lungs more space to fill the air -rich air. When one exhales, relaxes and pushes on the lungs and helps to eliminate waste gases such as carbon dioxide. It also exerts pressure on the abdominal cavity to help with other body functions such as throwing or urination. It is one of the few muscles that can work involuntarily and under human control. During sleep, the brain sends regular instructions for the membrane to download and relax, but the brain may suppress these instructions if one needs a breath.

engine and sensory signals

In addition to sending signals from the brain to the membrane, the phrenic nerves also Collet sensory signals that you can send back to the brain. This includes things, such as reports of whether to properly download, feel any pain and temperature of it and other organs and tissues in the chest. This allows mOzka correctly regulate breathing.

Causes of damage

diseases affecting phrenic nerves are specifically unusual; Nerve diseases are usually systemic and affect the whole body. Physical trauma causes most cases or direct damage to these nerves. This usually occurs when a person has a neck injury, or if the surgeon accidentally damages them during chest or abdomen surgery.

Symptoms of irritation and damage

irritation of frenic nerves can cause some unusual symptoms. It can trigger a reflex hiccup, a sudden, involuntary contraction of the membrane that causes the lungs to occupy a small sip of air. A less common symptom is pain on the tip of the shoulder blade, dump as a Kehr's sign. This type of pain can also have other serious causes and should be evaluated by a healthcare worker.

The symptom of frenic nerve damage is difficulty breathing. Because there are two of these nerves, one will still be able to breathe if someone is damaged, andle it will be difficult. Damage to both nerves is a medical emergency because the membrane will be paralyzed and one will not be able to breathe.

Treatment

breathing problems from frenic nerve damage can be solved in themselves, as the nerves can potentially regenerate and establish new connections. However, anyone who has difficulty breathing should see the doctor to exclude other causes. If a person has a continuously breathing difficulty associated with damage to the frenic nerve, a respiratory pacemaker may have a surgically implanted, battery device that discharges regular electrical pulses that stimulate the membrane to close. Sometimes a procedure called plications is also used. This consists in surgical treatment of the membrane so that it remains more than usual, allowing the lung expansion more space.
