Cancer cells often exhibit increased mitotic figures, varying in size and shape. Tissues that are malignant usually display these characteristics, emphasizing their dysregulated growth and division patterns. Additionally, neoplastic tissues tend to have abnormal mitotic figures due to uncontrolled cellular proliferation.

How do you calculate a mitotic index?
To calculate the mitotic index, you count the number of cells undergoing mitosis in a given sample and divide this number by the total number of cells in the sample. The result is usually expressed as a percentage. Mitotic index is commonly used to assess the rate of cell division in tissues, especially in cancer research.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
Can all cells in an adult undergo mitotic division at any given time?
No, not all cells in an adult can undergo mitotic division at any given time. Some cells, like muscle and nerve cells, are in a non-dividing state (G0 phase) and remain that way for extended periods. Others, like skin and blood cells, continuously undergo mitotic division to replenish and repair tissues.
What kind of cells are post mitotic cells?
Secondary Data
The functions of mitotic cell division in the life cycles of an organism may include?
Mitotic cell division enables growth, tissue repair, and asexual reproduction in multicellular organisms. It ensures that daughter cells receive an exact copy of the genetic material from the parent cell, maintaining genetic stability. Additionally, mitosis plays a crucial role in the development and maintenance of an organism's tissues and organs.
What is mitotic lesion?
A mitotic lesion is one in which there is an increased rate of mitosis in cells. This can be indicative of cancer where there is abnormal proliferation of cells.
What is the order of these mitotic stages?
1.) fertilization of egg by sperm 2.) mitotic cell division of zygote 3.) differentiation of cells into tissues 4.) organ development
What is a chronic and sometimes acute relapsing skin disease caused by increased mitotic division of epidermal cells?
Psoriasis

What is a mitotic lesion?
A mitotic lesion is an abnormality in a cell that affects its ability to divide properly during mitosis. This can lead to errors in chromosome segregation and potentially result in genetic mutations or cell death. Mitotic lesions are associated with conditions such as cancer and developmental disorders.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
How does the mitotic cell division relate to the cell cycle?
It still needs cells to form the organism. If cells aren't present, tissues won't be formed organs won't form to make organ systems and make organisms. THE CELL CYCLE cells-->tissues -->organs-->organ system-->organism
Why would the mitotic index be relevant to a diagnosis of breast cancer?
Because cancer is uncontrolled mitosis of cells; thus if the mitotic index of the breast cells in question is outside the normal range (above it, generally), then this would suggest increased rate of cell proliferation which could indicate cancer.

Cells that undergo mitotic division but not meiotic division are called?
Somatic cells undergo mitotic division but not meiotic division. Meiotic division is only seen in germ cells to produce gametes.
Mitotic cell division is very important for overall body what?
Mitotic cell division plays a crucial role in growth, development, and repair of tissues in the body. It ensures that cells can replicate and maintain tissue homeostasis, enabling processes such as wound healing and organ regeneration. Additionally, it is essential for proper development and growth of multicellular organisms.
