Spine cells do not reproduce asexually, infact the mitochondria of the male cells secret sperm that is absorbed through the cell membrane and then absorbed by the centrioles of the female cells. This tells the female cells to begin cell division. So though it is like normal cell division it is done sexually
the axon terminal button receives stimuli and passes it on to ither cells or it reaches the dedrites which are buried in your spine, travelles up the spine and reaches the brain, which is how you feel pain and things like that.
Cells do undergo mitosis regularly. This is because cells are always dying and need to be replaced. However, there are certain cells that are commanded by the brain, or have special genetic coding that instructs them to stop multiplying. For instance, cells in the nervous system and spine do not multiply after birth. That is why damage to the spine is so irreversible.
