Peripheral Nerve Injury - Anatomy - Sutherland Classification | Peripheral Neuropathy|

Peripheral nerves send messages from your brain and spinal cord to the rest of your body, helping you do things such as sensing that your feet are cold and moving your muscles so that you can walk. Made of fibers called axons that are insulated by surrounding tissues, peripheral nerves are fragile and easily damaged.
A nerve injury can affect your brain's ability to communicate with your muscles and organs. Damage to the peripheral nerves is called peripheral neuropathy.
Symptoms
With a peripheral nerve injury, you may experience symptoms that range from mild to seriously limiting your daily activities. Your symptoms often depend on which nerve fibers are affected:
Motor nerves. These nerves regulate all the muscles under your conscious control, such as walking, talking, and holding objects. Damage to these nerves is typically associated with muscle weakness, painful cramps and uncontrollable muscle twitching.
Sensory nerves. Because these nerves relay information about touch, temperature and pain, you may experience a variety of symptoms. These include numbness or tingling in your hands or feet. You may have trouble sensing pain or changes in temperature, walking, keeping your balance with your eyes closed or fastening buttons.
Autonomic nerves. This group of nerves regulates activities that are not controlled consciously, such as breathing, heart and thyroid function, and digesting food. Symptoms may include excessive sweating, changes in blood pressure, the inability to tolerate heat and gastrointestinal symptoms.
You may experience a range of symptoms because many peripheral nerve injuries affect more than one type of nerve fibers.
Causes
Peripheral nerves can be damaged in several ways:
Injury from an accident, a fall or sports can stretch, compress, crush or cut nerves.
Medical conditions, such as diabetes, Guillain-Barre syndrome and carpal tunnel syndrome.
Autoimmune diseases including lupus, rheumatoid arthritis and Sjogren's syndrome.
Other causes include narrowing of the arteries, hormonal imbalances and tumors.
