What cells will not continue to divide skin cell nerve cell epithelial cells lining the cheeks all of these?
Nerve cells typically do not continue to divide once they are fully formed. Unlike skin cells and epithelial cells that undergo continuous division for repair and maintenance, nerve cells have limited regenerative capacity. Once nerve cells are damaged or lost, they are not easily replaced, which contributes to the challenges of nerve regeneration in the body.
Can nerve cells reproduce and regenerate in the human body?
Nerve cells, also known as neurons, generally do not reproduce or regenerate in the human body. Once they are damaged or lost, they are not easily replaced. This is why injuries to the nervous system can have long-lasting effects.
Which cells in your body are never replaced?
Cells
Can nerve cells divide and regenerate in the human body?
Nerve cells, or neurons, generally do not divide and regenerate in the human body. Once they are damaged or lost, they are not easily replaced. However, there are some regions in the brain where new neurons can be generated through a process called neurogenesis.
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.
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.
What will not happen if a nerve cell is damaged?
Nothing dangerous will happen except for that area where the nerve is damaged it will probably hurt but usually it will heal and it will seem like nothing has happened. But if the cells are damaged badly you won't have any feeling in the part of the body where the cells are damaged. Also the cell may not regenerate.
Can the nervous system repair its cables?
The nervous system is comprised of nerves called neurons, not 'cables'. Different nerve cells can reproduce to create newer nerve cells to replace damaged cells.
When cardiac cells are damaged by a heart attack they are replaced by?
Fibrosis occurs, so fibres replace the cells
When cardiac muscle cells are damaged by a heart attack they are replaced by?
scar tissue.
Why can't a damaged cell in the brain be replaced?
Damaged cells in the brain cannot be replaced because the brain lacks the ability to regenerate cells like other organs in the body. Additionally, the complex network of neurons in the brain makes it difficult for new cells to integrate and function properly. Research is ongoing to find ways to stimulate brain cell regeneration, but it remains a challenging area in neuroscience.
What replaces dead or damaged cells?
Dead or damaged cells are replaced by nearby healthy cells that divide and multiply to fill in the empty space. In some cases, stem cells can also differentiate into the specific cell type needed to replace the damaged cells.
