Question

Do all cells in an animal body undergo mitotic cell division? If not give examples.

Answer 1

not all of them. egg cells/sperm sells are created by meiosis, not mitosis.

also, since red blood cells don't have nuclei, they do not undergo any type of cell division.

Answer 2

All, with the following exceptions:  

Nerve cells, once formed, do not undergo mitosis and do not die until the organism dies.  If a nerve cell dies for any reason, it is not replaced.

s*x cells (spermatozoa and ova), in their final stage, undergo meiosis instead of mitosis.  This results in a cell with a half-strand of DNA, so that it can join with another s*x cell (one spermatozoon and one ovum) to form an embryo, a new unique member of the species.

Red blood cells cannot undergo mitosis because they have no nucleus.

Answer 3

Some cells, once mature, have historically been considered unable to divide, like nerve and muscle cells.  This is why paralysis happens - the cells don't replace themselves once damaged.

However, fortunately current research is gathering evidence that sometimes these cells can divide and working on methods for encouraging that division.
