a Wolf-Rayet nebula is primarily shaped by the tremendous heat and wind of its own central star

I have trouble getting my head wrapped round the way that things work on these scales.

If the nebula has something like a 40 light year radius, does that mean that the glow from the nebula has actually been created by radiation that left the star 40 years previously? Or does the nebula glow because it is composed of hot plasma from the star?
