What is a nerve root?

The nerve root is the basis of the nerve when it leaves the central nervous system. Once the nerve is outside the central nervous system, it branches to allow a number of smaller nerves to distribute information throughout the body area that is innervated by this nerve. Disorders involving the central nervous system can affect the nerve roots, and the individual roots of the nerves can also be affected by congenital conditions, trauma and degenerative diseases that lead to damage.

There are two types of nerve roots. The roots of the cranial nerves are found in the skull and come directly from the brain. There are 12 roots of cranial nerves that innervate different areas of the face. A large number of nerves in the face is necessary to perform a number of important functions, from the transfer of visual information from the eye to the control of the muscles used for speaking and eating. Most of these nerve roots come from the brain stem.D, based on vertebrae to give different areas of the body. Each spinal nerve root consistsRVO and motor nerve that leaves the vertebra and then connects to form a nerve root. Ventral nerves contain motor neurons used for movement, while dorsal nerves have sensory neurons that mediate sensory information into the brain and brain.

In the case of spinal cord, compression or fractures of vertebrae can damage the nerve roots. This leads to symptoms such as armor, numbness, poor engine control, loss of feeling and sometimes paralysis of the body area administered by nerve root. When the spine is broken, the postponement of the spinal cord, the nerve roots under the fracture can no longer communicate with the brain, and the patient develops paralysis in areas that used these nerves.

Problems that may develop on the inclusion of the nerve rooteude degenerative disease that attacks the nerves or protective cover, which is scared, along with damage caused by trauma. Brain injury can lead to worsenedThe communication between the brain and the nerve roots, leading to a loss of feeling and other symptoms. When people develop neurological symptoms that indicate that there is a problem in the nervous system, diagnostic testing is used to determine the location of the problem, so it can be solved in treatment. This testing may include medical imaging, physical examination and electromyograms to study power lines in the nerves.
