What types of cells in your body are no longer undergoing mytosis?
Mytosis is spelt mitosis... and I believe it is brain cells
the cell theory was developed by?
the cell theory was develope by a Scottish biologist name Robert Brown.
To determine which types of cells in the body are no longer undergoing mitosis, you need to consider the concept of cell cycle and differentiation. Cells in the body have different life spans and purposes, which affects their ability to undergo mitosis.
Mitosis is a process by which a single parent cell divides into two identical daughter cells with the same number of chromosomes. This process allows for growth, repair, and maintenance of tissues in the body. However, not all cells continue to undergo mitosis throughout our lives.
Some types of cells that no longer undergo mitosis include:
1. Neurons: These are the cells of the nervous system that transmit electrical signals. Once neurons mature, they commonly lose their ability to divide and rarely undergo mitosis. This is why any damage to nerve cells is often permanent.
2. Cardiac muscle cells: The cells of the heart, known as cardiomyocytes, typically stop dividing shortly after birth. This means that the heart muscle cells do not undergo significant mitosis to regenerate or repair themselves in case of injury or disease.
3. Skeletal muscle cells: Similar to cardiac muscle cells, skeletal muscle cells, also called myocytes, largely stop dividing after development. However, in response to certain conditions like exercise, injury, or excessive load, they can undergo limited regeneration.
4. Red blood cells (RBCs): These are responsible for carrying oxygen throughout the body. Red blood cells lack a nucleus and DNA, making them incapable of undergoing mitosis. Instead, new RBCs are produced in the bone marrow from stem cells through a process called erythropoiesis.
It's important to note that while these cells do not undergo mitosis, there are other processes involved in maintaining their population or replacing damaged cells. Additionally, certain conditions or diseases may trigger abnormal cell division in these cell types.
