Question
Are there cells in the body that do not undergo mitosis? If so name some.
Answers
GPT 3.5
Yes, there are cells in the body that do not undergo mitosis. Here are some examples:
1. Neurons: These are cells of the nervous system that transmit electrical signals. Neurons are typically formed during embryonic development and do not undergo mitosis in adulthood.
2. Cardiac muscle cells: Cardiac muscle cells, or cardiomyocytes, form the walls of the heart and are responsible for its contraction. These cells have very limited ability to regenerate and do not undergo mitosis in any significant capacity.
3. Red blood cells (erythrocytes): These cells are responsible for carrying oxygen throughout the body. Mature red blood cells lack a nucleus and cannot undergo mitosis.
4. Platelets: These are fragments of larger cells called megakaryocytes that are involved in blood clotting. Similar to red blood cells, platelets lack a nucleus and cannot undergo mitosis.
5. Skeletal muscle cells: Skeletal muscle fibers are formed during development and postnatal growth and do not undergo mitosis in adulthood. However, they can increase in size through a process called hypertrophy.
6. Mature adipocytes: Fat cells reach a certain size during development and generally do not undergo mitosis in adulthood. However, in cases of excessive weight gain, new fat cells can be formed from precursor cells.
It is important to note that while these cells do not undergo mitosis, they can still play essential roles in the body and have specific functions that contribute to overall health and function.
