Why nerve cells do not undergo cell division?
Answers
Answer:
they don't
Explanation:
Neurons, or nerve cells, do not undergo cell division because, like cardiac muscle cells, they are very specialized in their function. They are designed to carry nerve impulses throughout the body via biochemical messages that develop patterns and pathways over time. While they do have nuclei, they do not have centrioles, which are necessary for cell division. In general, once neurons have died, they are not rapidly replaced, which is why a patient with a brain injury often does not recover. However, it has been discovered that under some conditions, neural stem cells can produce new nerve cells if given enough time, and some recovery is then possible.
nerve cells lack centrioles
Centrioles in animal cell is necessary for cell division as it forms spindle and astral rays .
