In multiple sclerosis, nerve impulses fail due to the deterioration of myelin, which is essential for the proper functioning of neurons. Myelin's degradation results in disrupted communication between nerve cells, leading to various neurological symptoms. Understanding the role of myelin helps illustrate the impact of this disease on nervous system function. ;
In multiple sclerosis, the deterioration of myelin, which insulates neuronal axons, leads to short circuits in nerve impulses. This damage disrupts the efficient transmission of signals in the nervous system, resulting in various neurological symptoms. Therefore, the answer is B. myelin.
