Damaged cells of an organism are usually by mitosis?
Damaged cells of an organism are usually repaired through the process of mitosis, where the damaged cell divides and produces two identical daughter cells. This allows for the organism to replace the damaged cells with healthy cells, maintaining proper functioning of tissues and organs.
Which cells in your body have the least regenerative power?
Neurons in the brain and spinal cord have limited regenerative power compared to other cell types in the body. Once damaged, neurons do not easily replicate or regenerate, which is why injuries to the central nervous system can often have long-lasting effects.
Which cells in your body are never replaced?
Cells
Do braincells grow back?
No, brain cells do not regenerate or grow back once they are damaged or lost. However, other brain cells can sometimes compensate for the lost functions. It is important to protect and preserve brain health to prevent cell damage.
Why cant damaged brain cells be replaced?
the answer is yes damaged brain cells can be replaced.The brain's ability to act and react in ever-changing ways is known, in the scientific community, as "neuroplasticity." This special characteristic allows the brain's estimated 100 billion nerve cells, also called neurons (aka "gray matter"), to constantly lay down new pathways for neural communication and to rearrange existing ones throughout life, thereby aiding the processes of learning, memory, and adaptation through experience. Neuroplasticity is the saving grace of the damaged or disabled brain; without it, lost functions could never be regained, nor could disabled processes ever hope to be improved. Plasticity allows the brain to rebuild the connections that, because of trauma, disease, or genetic misfortune, have resulted in decreased abilities. It also allows us to compensate for irreparably damaged or dysfunctional neural pathways by strengthening or rerouting our remaining ones.
What cell never gets replaced?
That would be a brain cell.
Why cant a cell in the brain be replaced?
there are some cells in the body that after the are produced once, they can no longer reproduce. These cells are known as cells in the quiescent stage. They are permanantly in G0 phase.
What types of cells if damaged or injured does not reproduce itself and it lost forever?
Neurons in the central nervous system, such as in the brain and spinal cord, do not typically regenerate themselves if damaged or injured. Once these cells are lost, they are not replaced through cell division, making them more challenging to repair compared to other cell types.
What will happen to the heart if some of its cell is damaged?
the heart cant pump blood so easle

Almost every cell in the human body is replaced every few years through the process of what?
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.
If the brain is damaged can a new nerve cell grow?
No-- Nerve cells are one of the few kinds of cells that never regenerate or regrow.
Where does epilepsy effect?
Epilepsy is a disease caused by trauma to a spesific part of your brain, you can however be born with it as well, but it's still the same part (cell) of the brain that's damaged/ineffective.
Why sciencist are interested in stem cells?
a stem cell is the basic undifferentiated cell, meaning that it has the capability to become any cell in the body. scientists are interested by them because they can replace damaged cells, the most interesting use is to replace damaged nerve or brain tissue since those tissues do not repair themselves on their own and nerve cells don't divide. the potential for stem cell technology includes healing paralysis and brain damage.
When neurons die why are they not replaced?
ALZHERMERS SYNDROME in simple terms In these diseases, neurons- the brain cells responsible for receiving, processing, and transmitting information- die and are not replaced. The current scientific literature makes one thing plain. As yet, there is no unifying hypothesis for the causes of Alzheimer's disease, Parkinson's disease, or many rarer degenerative brain diseases that cause dementia
