Why is the cell cycle shorter in epithelial cells than in liver or muscle cells?
Epithelial cells continuously undergo cell division to replenish the epithelial lining, hence their cell cycle is shorter. Liver and muscle cells typically do not undergo frequent cell division unless there's injury or growth requirement, leading to a longer cell cycle. Additionally, differences in gene expression and regulatory mechanisms can also contribute to the varying cell cycle durations.
In which cell there is no cell division?
Nerve cells (neurons) do not undergo cell division. Once they are formed during development, they remain in their post-mitotic state and do not replicate.
What do liver cells do during mitosis?
During mitosis, liver cells undergo cell division to produce two identical daughter cells. This process allows the liver to regenerate and maintain its functionality. Liver cells replicate their DNA, distribute their chromosomes equally, and then divide to ensure the continual renewal of liver tissue.
Bob had a cyst removed from his liver The doctor told him the liver cells would grow back and repair the area These liver cells will conduct what to grow back?
The liver cells will undergo regeneration to grow back and repair the area where the cyst was removed. Liver cells have a high capacity to regenerate, allowing them to restore normal function to the liver after injury or surgery.
Do liver cells divide?
Yes, liver cells are capable of division. This process, known as mitosis, allows liver cells to regenerate and repair damage. However, the rate of cell division in the liver is lower compared to other tissues like skin or intestines.
How is the binucleate condition of liver cells explained?
The binucleate condition of liver cells is due to incomplete cytokinesis during cell division, resulting in the retention of two nuclei in a single cell. This allows for continued cell function and growth without the need for increased cell division. It is a unique adaptation that helps liver cells maintain their metabolic functions.
Do liver cells also stop dividing after birth?
No, liver cells can continue to divide and regenerate throughout life. However, the rate of cell division decreases with age and liver damage can affect the regenerative capacity of the liver cells.
What is a nodular liver and cirrhosis of liver?
A nodular liver typically refers to the presence of multiple small nodules on the liver surface, which can be a sign of advanced liver disease like cirrhosis. Cirrhosis is a late stage of scarring of the liver caused by many forms of liver diseases and conditions, leading to loss of normal liver function. It can be caused by alcohol abuse, chronic viral hepatitis, or other conditions.
Why does a skin cell divide more often than liver cell?
As far as I know, liver cells usually only undergo mitosis if the liver is damaged. You should check a few other sources though.
How do rbc's divide?
Red blood cells, or erythrocytes, do not undergo cell division as they lack a nucleus. They are produced by the bone marrow through a process called erythropoiesis, where hematopoietic stem cells differentiate and mature into erythrocytes. Once mature, red blood cells circulate in the bloodstream for about 120 days before being cleared by the spleen and liver.
These cells use mitosis to divide into two daughter cells?
Cells that undergo mitosis to divide into two daughter cells are typically somatic cells, such as skin cells, muscle cells, and blood cells. Mitosis is a form of cell division that results in genetically identical daughter cells for growth, repair, and maintenance of the organism.
Are hepatocytes labile or stable type cells?
Hepatocytes are labile cells, meaning they have the ability to regenerate and replicate in response to injury or damage. They are capable of self-renewal and rapid cell division to restore liver function.
