What Does “Amyotrophic Lateral Sclerosis” Mean?
A-myo-trophic” comes from the Greek language. “A” means no or negative. “Myo” refers to muscle, and “Trophic” means nourishment—“No muscle nourishment.” When a muscle has no nourishment, it “atrophies” or wastes away. “Lateral” identifies the areas in a person’s spinal cord where portions of the nerve cells that nourish the muscles are located. As this area degenerates it leads to scarring or hardening–“sclerosis”–in the region.
