Mature cells can't grow back, in other words divide or reproduce. This means that when a
person gets severe burns, or brain damage, the cells won't come back and the person
might be paralyzed or have no feeling in a certain area. So if it was possible for nerve cells
to divide, they person wouldn't have any problems and could heal themselves.
Because if that can be done it could be used to repair nerve damage.
Since nerve cells don't usually divide when they are fully mature, there is no function for them at that time. However, they did at one time need them and they are left in place.
mitosis
The slowest dividing cells in the human body are the nerve cells. Nerve cells generate and conduct electrical impulses, allowing communication between the central nervous system and the rest of the body.
Nerve cells have non-functional centrosomes. Thus they are incapable of dividing.
As yet, scientists are not certain how stem cells know what type of cell to become. All they can be sure of at the moment is that they respond to signals received from other, often neighbouring, cells.

Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
Nerve cells will most likely NOT continue to divide.
Are permanently in a state of nondivision.
neurons (nerve cells)
mitosis
Well, the human body contains a lot of neurons. Neurons also send signal to other neurons. so i don't think that neurons divide, but what i do know is that our neurons in the brain starts to develop during Embryonic development. i hope this help you with your question.

A nerve cell is likely to not continue to divide.
Muscles cells can undergo mitosis, but almost all nerve cells will not. This is true within the body and even when isolated and put into culture.
