Question

this is an example of an autoimmune disease. the antibodies produced by lymphocytes (a type of white blood cell) mark myelin as something that should not be in the body. this causes inflammation and the destruction of the myelin in the central nervous system. as the insulation around the axons is destroyed by the disease, scarring becomes obvious.
a cp
b ms
c gb
d emg

Explanation:

• CP (Cerebral Palsy): It is a group of disorders affecting a person's ability to move and maintain balance and posture. It is caused by damage to the developing brain (usually before birth), not an autoimmune - mediated destruction of myelin.
• MS (Multiple Sclerosis): It is an autoimmune disease. In MS, the immune system (specifically, antibodies produced by lymphocytes in some cases) attacks the myelin sheath (the insulation around axons) in the central nervous system. This leads to inflammation, destruction of myelin, and scarring (sclerosis).
• GB (Guillain - Barré Syndrome): It is an autoimmune disorder that affects the peripheral nervous system. The immune system attacks the nerves in the peripheral nervous system, not the myelin in the central nervous system.
• EMG (Electromyography): It is a diagnostic test, not a disease. It measures the electrical activity of muscles.

Answer:

B. MS
