Myelin is the insulating "sheath" that surrounds nerves in your body. When the myelin breaks down, false signals make it into the nerves, sometimes causing pain, and sometimes causing muscle spasms.

Signal propagation in the affected nerves would be slowed or nearly stopped. Movement and senses would become limited.

Motor neuron involve the muscles. If they are damaged, then the muscle that they are connected to will not work.
PLS affects a part of the neuron called the cell body (or soma). Specifically, it is the cell bodies of upper motor neurons that are affected.

poliovirus invades the nerve cells of the spinal cord and kills the motor neurons. When the motor neurons are destroyed, the muscles they connect to become damaged and weaken. The result is varying degrees of paralysis, including difficulty swallowing
breathing would cease
damaging or killing neurons and neuroglia in the affected areas
When you are hit in the head, both neurons and axons can sustain damage. Neurons are the specialized cells responsible for transmitting electrical signals in the brain, while axons are long, slender projections that extend from neurons and transmit those signals to other neurons or tissues. Impact to the head can cause direct damage to neurons and axons, leading to functional impairment or cell death.
Often, a disorder of the motor neurons results in progressive muscle atrophy (shrinking and wasting) of some, if not all, the muscles of the body. Muscle twitching (fasciculation) is common among these disorders
They looked like neurons.
