Answer: C)Nerve conduction
Explanation:
Multiple sclerosis is a disabling disease of the brain as well as the spinal cord. In short, it affects the spinal cord. In multiple sclerosis, the immune system of the body affects self cells. This condition affects the coordination between the brain and the rest of the body. In multiple sclerosis, the mylein sheet that covers the nerve fibers that connect the brain and spinal cord are affected by the immune system.
The oligodendrocytes are the cells that form the myelin sheet. Further, the myelin sheet contains the nerve fibers. Hence, nerve conduction will also get affected by this disease.
Joints, cartilage, ligaments, and bursae.
