the nerve cells in the human nervous sytem seldom undergo mitosis.?

Question

explain why complete recovery from injuries to the nervous system may not occur.

Answer 1

Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell. The word "neuroglia" means "nerve glue." These cells are nonconductive and provide a support system for the neurons. They are a special type of "connective tissue" for the nervous system.
Neurons

Neurons, or nerve cells, carry out the functions of the nervous system by conducting nerve impulses. They are highly specialized and amitotic. This means that if a neuron is destroyed, it cannot be replaced because neurons do not go through mitosis.

Answer 2

The nerve cells in the human body don't undergo mitosis because that is the way that they are constructed. Unlike cancer cells, which divied rapidly, nerve cells stay in interphase for a long time, and may divide once in a human's life span. Cancer cells, or cancer infected cells undergo mitosis rapidly and hardly spend any time in interphase. Normal cells spend around 70% of their mitotic cell division in interphase.

Nerve cells don't divide rapidly. Around the age of 10, your nerve cells stop dividing. So...if you have a spinal injury, and your nerve cells aren't dividing, then you will unlikely heal your spine, and you will probably stay injured for the rest of your life.

Answer 3

nerve cells never go to division wether mitosis or meiosis.but a nerve cell can repair itself only if the cell body of the cell is not damaged note:> but if you talk about the mitosis ever happened in life history of nerve cells then yah it happens during body formation at embryo stage.
