In a split of a second, your body reacts to any interference that it comes into contact with. Whether reflex or predetermined, this defensive action is enabled by the nervous system.
What is the nervous system?
This system consists of the brain and spinal cord (central nervous system) and nerves (peripheral nervous system).
Divisions of the nervous system.
The nervous system has two divisions; The voluntary division concerned with movement and sensation, and Autonomic system concerned with reflex functions. The autonomic system has 2 branches; sympathetic and the parasympathetic branches. The sympathetic branch activates the glands and organs that defend the body against attack. The parasympathetic system of the nerves is concerned with
nourishing, healing and regeneration of the body. Nerves mapped everywhere your body, are the contact points to the brain. Outgoing nerves are called peripheral nerves,responsible for controlling your skeletal muscles. Susceptible to various diseases and conditions, the nervous system remains extremely vulnerable.
Health risk factors (causes) of the nerves.
Possible causes of nerve pain and nerve damage are autoimmune diseases ,cancer, trauma or compression of nerves , diabetes, toxic substances,motor neuron diseases , nutritional deficiencies. Infections cause several disorders such as such as meningitis and polio, functional disorders such as epilepsy, structural disorders such as spinal injury,vascular disorders such as stroke and degeneration such as multiple sclerosis.
What diseases affect the nerves?
Some of the diseases and conditions that affect the nerves are Stroke, Nervousness, Depression, Stress, Epilepsy, Alzheimer’s disease, Schizophrenia, Parkinson’s disease, Dementia, Reynaud’s syndrome, Neuralgia among others. Middle aged persons are more susceptible to Parkinson’s disease and Reynaud’s syndrome . Manifested through colour change, Reynaud’s syndrome causes the hands to turn white, purple or red as a due to spasms within the body. It is more prevalent in post menopausal women. Parkinson’s disease affects those in their 50’s. It is characterized by loss of voluntary movement, tremor and muscle rigidity. Alzheimer’s disease characterized by confusion, memory loss and depression, is caused by the degeneration of brain cells. Schizophrenia is a hereditary mental disease. It is manifested by changes in personality and hallucinations. Epilepsy is characterized by loss of memory, seizures, absent-mindedness and convulsions. It affects the functionality of the brain. Nervousness, depression and stress are other conditions that affect the nervous system. Nervousness is accelerated by stimulants, drugs, lack of sleep or physical exercise. Depression and stress are caused by various events of life. Whether physical, emotional or physiological stress, it takes toll on the nervous system, immune system and metabolic system. Mental fatigue, migraines and headaches, usually accompanied by nausea and blurred vision are other conditions that affect the nervous system. In women, they may be caused by menstruation. Stroke; either mild or fatal, is caused by deprived circulation of blood to the brain. This could be due to a broken artery or clotting. Dementia; a gradual and irreversible nervous system attacking disease, affects the functionality of the brain. It does result to loss of mental ability. chilblains; caused by inadequate blood circulation to the skin, are manifested by swelling, itching and inflammation of the hands and feet. Tightening of shoes can result to this condition. Do you always feel a sharp, burning pain along the course of your nerves? It could be Neuralgia.
Treatment , diagnosis and management of nervous system diseases.
Treatment and diagnosis techniques of these nervous system diseases are ; imaging tests such as computed tomography or CT, magnetic resonance imaging (MRI), angiography, positron emission tomography, and Doppler ultrasonography. It is important to consume healthy balanced diets in order to improve your general health. Nutrition helps in the development of brain cells. It also ensures your nerve fibres are well insulated and protected. Nutrients facilitate communication between cells and supports electrical nerve impulses.
- Do regular physical exercises, exercise your nerves by solving puzzles and quizzes.
- Avoid or moderate exposure to adverse environments.
- Regular medical check ups will help prevent and diagnose any disease.
