Examples of peripheral nerve disorders include: Pain receptors in the skin can also become over-sensitized, so that people may feel severe pain from stimuli that are normally painless (for example, some may experience pain from bed sheets draped lightly over the body). Peripheral neuropathy involves damage to the peripheral nerves that transmit pain and temperature sensations, and can prevent people from sensing that they have been injured from a cut or that a wound is becoming infected. Rather, the disease causes varying degrees of weakness, depending on the type and severity of the neuropathy. It can cause paralysis if a nerve is completely lacerated, although total paralysis is rare in people with neuropathy. Neuropathy is a disorder that prevents nerves from functioning properly. The other components of this peripheral system are the neuromuscular junction where the nerve meets the muscle and the muscle itself. Motor nerves carry bioelectrical information to muscle, resulting in contraction and movement.

Information regarding the environment such as hot, cold, and the position of our pen are carried on sensory nerves. These nerves are considered the peripheral nervous system. Incoming and outgoing information travel in the nerves of the arm similar to a telephone wire. The brain and spinal cord are considered the central nervous system.

Similar discomfort may be brought on by sleeping on an arm or leg in a funny position. Many of us have experienced severe burning, numbness, and tingling after hitting our “funny bone.” This is caused by trauma to the ulnar nerve at the elbow.
