Give an example of two types of cells that never go through cell division once fully formed.

The two types of cells that never go through cell division once fully formed are nerve cells and muscle cells.

Explanation:

The nerve cells and the muscle cells not undergo cell division after formation, because they can never re grow or cannot be repaired once they are mature. We should take good care of it once they are matured. They just under division from being baby to teenagers after that they stop undergoing cell division. This is true for both elephants as well as human beings. This thing is also applicable in case of bones.
