1) What cells in the body do not regenerate and why?
For the past several decades, scientists belived that brain cells do not regenerate . take a look of this

But now some researchs show that they can regenerate in some case

2) What cells the body are multinucleated and why?
Skeletal muscle fibers are multinucleated, with the cell's nuclei located just beneath the plasma membrane. In the developmental process, a skeletal muscle fiber is made by combining cells, so it develops into a multinucheated cell.

Hope that helps

Next time, try to do your own homework. These are things that can be found on the internet.

If i don't remember wrongly, my lecturer told us that heart cells do not regenerate, which is why you don't hear of cases of "cancer of the heart".
