Nervous System and Nerve Pain

The Nervous System in the Human Body

Did you know nerves can grow back and heal? We are born with a fixed number of nerve cells called neurons. While neurons cannot replicate like skin and liver cells can, they can regenerate. The human nervous system divides into the central and peripheral divisions. While both divisions are capable of growing and healing damaged nerves, this is a much more efficient and successful process in the peripheral nervous system.

How Neurons Work

Neurons is the basic unit of the brain and is specialized to transmit information to other nerve cells, muscles and gland cells. Neurons have a cell body and an extension called axons. Once the cell body dies, the neuron can not recover and dies. But if the axon is damaged, it can regenerate and heal itself over the course of time in a fairly slow process usually taking several months to two years. Nerve axons can be damaged in a number of ways, such as repetitive use of a joint or spinal vertebrae that may pinch the nerve, or a traumatic impact such a sports injury or car accident.

Nerve Pain & Nerve Damage

The notion of nerve pain depends on the location of the nerves. There are three types of nerves in your body, the autonomic nerves, the motor nerves, and the sensory nerves. The autonomic nerves regulate involuntary activities like heart rate, blood pressure, digestion, and temperature regulation. Motor nerves control movements by sending information to your muscles. And sensory nerves pass information from your skin and muscles to your brain which allow you to feel sensations and sometimes pain.

Motor nerve damage can cause weakness, muscle atrophy, twitching and possible paralysis. Sensory nerve damage will be painful with increased sensitivity, as well as numbness, tingling / prickling and burning sensations. The spinal cord nerve endings being pinched or damaged will effect these two types of nerves, sensory and motor. That’s why when you have a herniated disc, or suffer from degenerative disc disorder, you may have pain, as well as weakness in your legs.

You will have to speak to a doctor in order to fully diagnose what may be the cause of pain, and find out what kind of treatment options are available to you.
