What is a radial nerve?
Radial nerve is a nerve found in human arm. This is the nerve responsible for providing the nerve supply of the forearm as well as the rear partition, also called the extensor compartment. This section holds muscles that are supplied by radial nerve. This nerve also enters the bone into the arm known as Humerus.
triceps brachii is a primary muscle supplied by a radial nerve. Other muscles are supplied by this nerve at least partially. Triceps Brachii is a large muscles with three heads located on the back of the upper arm. This is the muscles that allows to straighten the arm.
The radial nerve begins in the structure known as the brachial plexus. It is a network of nerve fibers of passengers from the spine and throat, armpit area and then into the arm. The brachial plexus is responsible for ensuring the nervous muscle supply and the skin of the arm.
due to the importance of radial watch for the human body, injuries involving this nerve has the potential to endanger the normal motor and sensory function, especially including the arm. Humerusis the bone found at the top of the arm. When the radial nerve is inserted into this bone, the fracture may lead to nerve damage.
prolonged pressure on the radial nerve may also cause injury or dysfunction. Some causes of this pressure include wearing a watch band too tight or sleeping in a position that limits the nerve. The health condition known as ischemia can also prevent the proper functioning of the nerves. Ischemia causes incorrect blood flow to the nerve and surrounding areas.
Some symptoms that may indicate nerve dysfunction involving radial nerve, include pain or numbness, especially in hand, or difficulties in attempting to extend the wrist or elbow. Abnormal feelings such as tingling or feelings of pegs and needles can also present. Any of these symptoms should be reported to a medical expert to obtain the correct diagnosis.
Treatment of nerve dysfunction depends on the cause andon individual responses to treatment options. The only necessary treatment is often a change in actions or positions that lead to the onset of symptoms. In other cases, drugs are prescribed in an effort to reduce pain or swelling associated with nervous dysfunction. Physical therapies or appliances such as braces or splints often reduce symptoms and accelerate the healing process. Surgical intervention is only necessary to repair nerve or surrounding tissues.
