Nervous Systems – what is a nerve?
Neurons and nerve cells
The basic unit of nervous system is the neuron or nerve cell. A nerve is one or more bundles (fasciculi) of fibers; each fasciculus contains microscopic nerve fibers, each enclosed in a neurolemmal sheath. The nervous system is an extensive network. It is the body’s control panel. It conducts information that controls, regulates and coordinates; by way of impulses all functions of the entire body. The nerve impulses communicate to your muscles and organs as to how to respond to the environment.
There are three parts of the nervous system that have to work together:
Central Nerve Disorders
Some central nerve disorders can be cause by: stroke, multiple sclerosis, tumors, epilepsy, brain or spinal cord trauma or Parkinson’s disease.
Some peripheral nerve disorders can be hereditary, others can be cause by a simple sport injury. The sport related injury is called “burners” or “stingers” which is usually an injury of the nerve(s) between the neck and shoulder.
Other peripheral nerves may be damaged through medical conditions as diabetes or auto-immune diseases as rheumatoid arthritis. Some can occur from alcoholism or a vitamin deficiency.
Eat healthy, take proper vitamins, minerals and supplements, avoid alcohol, quit smoking and exercise. Massage is a good way to improve circulation and avoid applying prolonged pressure to nerve points.
