What is a peripheral nerve?

Peripheral nerve is a conglomeration of nerve fibers that transmit messages to and from the spinal cord. They consist of peripheral axons, which are small extensions of neurons, which can be up to 3 feet long (0.91 meters). Peripheral nerves, faithful to their name, are located in the peripheral nervous system, nerves outside the brain, backbone column and automatic nervous system. The messages are transmitted using nerve fibers that are grouped into bundles that resemble cables. Peripheral nerves come in different sizes; Some are as large as the 0.4 inches (1 centimeter) in diameter, while others require the microscope to see correctly.

Information mediated by the peripheral nerve is transmitted at lightning speed. Usually the pulses can be sufficiently transported per second. Certain neurons works at a speed of up to 120 milliseconds. Correct healing can be achieved by congenital peripheral nerve skills during regeneration. If the peripheral nerve is interrupted, the associated axons erode and die. Fortunately with the axons,which are located closest to the spine, growing at approximately 0.04 inches (1 millimeter) daily. Although the recovery process may be lengthy, most patients suffering from peripheral nerve injuries cause complete or almost complete recovery.

The peripheral nerve damage may be caused by different conditions. The most common are physical injuries, infections, diabetes and autoimmune diseases. Pain associated with these conditions may be intense and often occurs in other areas of the body than in the center of the peripheral nerve. This phenomenon calls pain where peripheral nerves draw other nerves in the body to its compromised condition.

One of the most serious types of peripheral nerve damage can be caused by cancer. Damage to this kind is rarely reversible. When cancer begins to influence peripheral nerves, the disease has advanced to the critical phase and the prognosis is generally grim.

some patientEven with peripheral nerve damage, they may be entitled to remedial surgery, although a number of factors must usually be fulfilled. If the injury caused paralysis or weakness for a longer period of time, usually three months or more, the patient may be considered for surgery. Another factor in determining the appropriateness for surgical option is the scope of neurological deficit caused by nerve damage.
