More than you can imagine. Over trillions
Neurons in the brain and spinal cord are cells in the body that are never replaced.

It all depends on which cells. Some are not replaced. These are mostly nerve cells such as found in the brain. Other cells constantly die and are shed and replaced from tissues below them. An example of this are your skin cells.
Almost every cell in the human body is replaced every few years through the process of cell division and renewal. This process is called cell turnover, where old or damaged cells are constantly being replaced by new cells to maintain the integrity and functionality of tissues and organs.
the brain cells cannot be replaced by the human body, that's why the boxer who gets brain cells damage can never be illed.
