Detailed explanation-1: -Neurons cannot divide because they lack centrioles. Each nerve cell has a specific place in our nervous system.
Detailed explanation-2: -Nerve cells do not divide as they do not contain centrioles so why does plant cells divides (even they do not contain centrioles)?
Detailed explanation-3: -Permanent cells are cells that are incapable of regeneration. These cells are considered to be terminally differentiated and non-proliferative in postnatal life. This includes neurons, heart cells, skeletal muscle cells and red blood cells.
Detailed explanation-4: -Nerve Cells Do Not Renew Themselves They do not divide at all. There are very few exceptions to this rule – only two special places in the brain can give birth to new neurons. For the most part though, the brain cannot replenish dead neurons.
Detailed explanation-5: -There is absence of centrioles in the nerve cells and because of this they are unable to perform mitosis and meiosis and hence these cells do not divide. But nerve cells get longer without dividing and they do not divide during their lifetime.
