The central and peripheral nervous systems

Damage to nerves can be severe. Because of their structure and function, nerves do not heal as quickly as some body parts do, but sometimes nerve damage can heal on its own.

Damage to nerves can be severe. Because of their structure and part, nerves do not heal as quickly as some body parts practise, but sometimes nervus damage can heal on its own.

Nerves are the advice system of the body. They comport letters between the brain and spinal cord and all parts of the body. Damage to nerves tin can be severe. Because of their construction and function, fretfulness do not heal as rapidly every bit some body parts do. But sometimes nerve damage can heal on its ain.

The nervous arrangement consists of 2 parts, the central nervous system, and the peripheral nervous organization. The key nervous system is made upwards of the brain and spinal cord, both protected past bony structures. The primal nervous system contains circuitous cells that don't reproduce themselves. For this reason, damage to the primal nervous system does not heal on its own.

The peripheral nervous organisation connects the central nervous organisation with the rest of the body. These nerves are non protected by bone and are easily damaged. They can repair themselves if the injury is not besides severe.

Types of nerve damage

3 types of impairment can occur to the peripheral fretfulness. Impairment can be caused by:

Cuts
Bruising or pressure
Stretching

A covering called the myelin sheath protects about fretfulness in the trunk. Commonly, stretching or bruising injuries damage the nervus fibers without dissentious the myelin sheath. The nerve fibers tin abound dorsum slowly. If the myelin sheath is damaged, every bit may occur with cut injuries, the nerves tin't heal themselves.

How nerves regenerate

A neuron or nerve cell has three main parts. It has a cell torso and short branches chosen dendrites that receive messages. The third part is a long cobweb called an axon that transmits messages. Nervus impulses travel down the axon to the stop, where they jump to the dendrites of the adjacent neuron. The signal where the nerve impulse is transmitted to the side by side nervus cell is called a synapse.

When a peripheral nerve is damaged, the body cleans up the damaged tissue. So damaged axons may regrow, beginning at the end nearest the brain. In time they may grow enough to re-establish a connection and permit the nerve to work again.

Symptoms of nerve impairment

There are 2 main types of fretfulness, motor and sensory. Motor nerves tell parts of the torso to move. Harm to a motor nerve can cause weakness and loss of function. Sensory nerves behave estrus, cold, pressure, pain, and other sensations. If yous damage a sensory nerve, you won't get accurate information nearly what is going on with your body.

Other symptoms of nerve damage can include:

Burning sensations
Pain
Numbness
Tingling

Diagnosis of nerve damage

An electric conduction exam can diagnose nerve harm. Sometimes a CT scan, MRI, or MRI neurography can also be helpful. These tests tin can show whether a nervus is likely to heal on its own or whether it may need surgery.

Doctors may apply the Sunderland classification system to describe nerve damage. The classifications are.

Get-go caste: You should rapidly recover from this blazon of injury, often within hours, although it may take a few weeks.
Second caste: This level of injury involves broken axons but should heal without surgery.
Tertiary degree: Harm is not bars to the axons. Sometimes the damaged area may demand to be cleaned up surgically or repaired.
Fourth degree: Damage is severe enough that the nerve volition not repair itself. Testing shows that no electrical free energy can pass downwardly the nerve pathways. This level of injury may require surgery with nerve grafting.
5th degree: These injuries involve laceration or severe stretching. The nervus has been split in two and requires surgery.

Acupuncture, massage, physical therapy, and other non-invasive strategies tin can be a function of the treatment for nerve harm. These therapies won't fix nerve damage but may promote healing.

Surgery for damaged fretfulness

If your nerve is unlikely to heal on its own, your dr. may offer surgery as an option. Normally, the surgeon begins past repairing the myelin sheath around the nerve. The nerve fibers should start to regrow within three to four weeks. Nerves typically grow about one inch a month. Every bit the nervus regrows, y'all may accept tingling in the expanse.

Sometimes surgeons have a nerve from some other part of the body to fix the damaged nervus. You lot may lose feeling in the area where the surgeon takes the graft.

Recovery from nerve surgery

Many factors influence the rate at which your nerves heal. These include:

Your age
Your general land of wellness
The quality of your slumber
Whether yous use booze, tobacco, or other substances
How well you follow your doctor's instructions

After surgery, information technology can take a year for a nerve to regrow completely. And then it can take another year or more than for the nerve to mature and for the nerve and muscle to form a skilful connection.

The encephalon may require training to recognize the new connection when healing is complete. Physical therapy can re-educate the brain.
