Which cell has highest mitotic index?

To replace the damaged cells, the cells of the skin undergo mitosis. So, skin exhibits the highest mitotic index.

What normal cells have the highest mitotic index?

Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Cancerous tissue would have a higher mitotic index because the cells are constantly dividing.

What has a higher mitotic index?

An elevated mitotic index indicates more cells are dividing. In cancer cells, the mitotic index may be elevated compared to normal growth of tissues or cellular repair of the site of an injury.

Which part of the root would have the highest mitotic index?

Root tip would be the place where the highest rate of mitosis is because this is where the tissues are continuously subject to damage.

What is a high mitotic rate?

The higher the mitotic count, the more likely the tumor is to have metastasized (spread). The logic is that the more cells are dividing, the more likely they will invade the blood or lymphatic vessels and thus spread around the body.

Do benign tumors have a high mitotic index?

Occasionally, the mitotic rate in benign tumors may be brisk, and those with mitotic activity up to 15 mitoses/10 hpf are termed leiomyomata with increased mitotic activity (Fig. 20.81; see Table 20.7).

What is a mitotic count?

Listen to pronunciation. (my-TAH-tik rayt) A measure of how fast cancer cells are dividing and growing. To find the mitotic rate, the number of cells dividing in a certain amount of cancer tissue is counted.

What is mitotic index its significance?

The mitotic index (percentage of cells in mitosis at any time) provides a measure of the capacity of cells to divide and of the rate of cell division. It is used to identify the sites of growth within a tissue and to determine which cell types are dividing.

How do you measure the rate of mitosis?

The growth rate of a eukaryotic population dividing at a constant rate can be estimated from the equation, tm/g ln 2 = ln (1 + R), in which tm is the time required for mitosis, g is the generation time, and R is the fraction of cells undergoing mitosis.

Which zone has the most mitotic activity?

What region of a root has the most mitosis activity? Why? The end has the most mitotic activity. The cells are going through later stages of mitosis.

What tissue has the highest rate of mitosis?

Skin cells, hair follicles and the cells lining our intestines (epithelial cells) all have high rates of mitosis as these tissues constantly need to be replaced. In plants growth occurs largely at the shoot and root tips. These cells have much higher rates of mitosis than the rest of the plant.
