Answer 2

Answer:

The cells that are most affected by Primary Lateral Sclerosis are muscle cells and neurons.

Explanation:

Primary Lateral Sclerosis (PLE) is a condition that affects the portion of the peripheral nerves that are responsible for innervating the striated muscles, producing muscle stiffness and paralysis.

The cause of PLE is unknown and it produces a degeneration of the supporting tissue —glial tissue— in the lateral portion of the spinal cord and nerves, which is in charge of activating the muscle tissue. As a result, the cells most affected are the neurons, which do not fulfill their function, and the muscle cells that tend to atrophy.

The other answer combinations are wrong choices because:

• Primary lateral sclerosis does not affect the epithelial tissue or the liver cell.
