What does the term cytostatic mean?

• A. Kills cells
• B. Prevents cell division
• C. Promotes cell division
• D. Enhances cell function

Answer: (B)

The term cytostatic refers to substances or treatments that prevent or inhibit cell division. This means that cytostatic agents can slow down or halt the proliferation of cells, which is particularly important in clinical contexts such as cancer treatment, where it is beneficial to stop the rapid growth of malignant cells. By targeting the mechanisms involved in cell division, cytostatic drugs help in managing conditions characterized by uncontrolled cell growth.

In contrast, other options focus on different effects: substances that kill cells would be termed cytotoxic, whereas promoting cell division or enhancing cell function relates to actions that either facilitate growth or improve cellular activity rather than inhibit it. Thus, the definition of cytostatic aligns precisely with the role of preventing cell division.
