ANATOMY

Detailed explanation-1: -Conduction velocity: impulses typically travel along neurons at a speed of anywhere from 1 to 120 meters per second. the speed of conduction is influenced by the presence or absence of myelin. Neurons with myelin (or myelinated neurons) conduct impulses much faster than those without myelin.

Detailed explanation-2: -What will happen to nerve conduction speed in affected neurons? It will slow down dramatically. Which of these diseases involves the destruction of the myelin sheath on certain neurons within the brain and spinal cord? Infants require many nutrients early in life, including lipids such as fats.

Detailed explanation-3: -Multiple sclerosis is a debilitating disease of the central nervous system that has been characteristically classified as an immune-mediated destruction of myelin, the protective coating on nerve fibers.

Detailed explanation-4: -When the myelin sheath is damaged, nerves do not conduct electrical impulses normally. Sometimes the nerve fibers are also damaged. If the sheath is able to repair and regenerate itself, normal nerve function may return. However, if the sheath is severely damaged, the underlying nerve fiber can die.
