Detailed explanation-1: -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-2: -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-3: -A demyelinating disease is any condition that causes damage to the protective covering (myelin sheath) that surrounds nerve fibers in your brain, the nerves leading to the eyes (optic nerves) and spinal cord. When the myelin sheath is damaged, nerve impulses slow or even stop, causing neurological problems.
Detailed explanation-4: -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.
