Verified step by step guidance

Identify the key characteristics of Multiple Sclerosis (MS) and Amyotrophic Lateral Sclerosis (ALS). MS is an autoimmune disease that affects the central nervous system, specifically targeting the myelin sheath of neurons. ALS is a neurodegenerative disease that primarily affects motor neurons in the central nervous system.

Understand the role of the central nervous system (CNS) and peripheral nervous system (PNS). The CNS includes the brain and spinal cord, while the PNS consists of nerves outside the CNS.

Analyze the statement that both MS and ALS primarily affect the peripheral nervous system. MS primarily affects the CNS, and ALS affects motor neurons, which are part of the CNS, although the effects can extend to the PNS.

Consider the statement that both involve the degeneration of motor neurons. ALS is characterized by the degeneration of motor neurons, while MS involves damage to the myelin sheath, not directly to motor neurons.

Evaluate the statement that both are neurological disorders affecting the nervous system. Both MS and ALS are indeed neurological disorders that impact the nervous system, though they do so in different ways.
