September 28,2015The central nervous system is made of numerous cells called neurons. Neuron consists of 2 parts - cyton (cell body) and axon. The axon is covered by myelin, which helps in the conduction of nerve impulses or signals between the neurons. In multiple sclerosis, myelin in certain parts of the central nervous system is destroyed thereby impairing the conduction of nerve impulses.
The exact cause of MS is not known, but some factors like immunity and genes are thought to play a role.
