Some people have good reflexes, Like say your friend is trying to sneak up on you. Then your brain tells you someone is coming. Your body react fast and see who's behind you. And this is true facts.

Now let's talk about the little soldiers helping the brain. They are called neurons or the nerve cells, they designed to transmit information to other nerve cells, muscle, or gland cells. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites.

The meninges are the protective coverings of the central nervous system (CNS). They consist of three layers: the dura mater, arachnoid mater, and pia mater.

“Of all the diseases of the nervous system, the most common difficulty that people have is pain, and much of that is nerve-related,” according to Dr. Shai Gozani, founder and CEO of Neuro Metrix, a medical device company. “There are 100 million people who live with chronic pain.”

According to the Mayo Clinic, patients with nerve disorders experience functional difficulties, which result in conditions such as:

Epilepsy, in which abnormal electrical discharges from brain cells cause seizures

Parkinson's disease, which is a progressive nerve disease that affects movement

Multiple sclerosis (MS), in which the protective lining of the nerves is attacked by the body’s immune system

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a motor neuron disease which weakens the muscles and progressively hampers physical function

Huntington's disease, which is an inherited condition that cause the nerve cells in the brain to degenerate

Alzheimer's disease, which covers a wide range of disorders that impacts mental functions, particularly memory.
