Which of the following statements is part of the Law of Bergonie and Tribondeau?

The Law of Bergonie and Tribondeau outlines key principles related to the radiosensitivity of cells and tissues. Among these principles, one important aspect is that radiosensitivity is closely correlated with the degree of mitotic activity within the tissue. Tissues with high mitotic activity, such as those found in rapidly dividing cells (e.g., skin, bone marrow, intestinal lining), are more sensitive to radiation compared to tissues that are less active in cell division.

This correlation is essential in understanding how different tissues respond to radiation exposure. Tissues that are actively proliferating are typically more vulnerable to the damaging effects of radiative processes because they are in a state of growth and duplication, increasing the chances of radiation affecting cellular DNA.

While the other statements touch upon relevant concepts—like the influence of the number of undifferentiated cells or the age of individual cells—those aspects are not as critically aligned with the core principles defined by Bergonie and Tribondeau as the relationship between radiosensitivity and mitotic activity is. Therefore, the choice that emphasizes mitotic activity accurately reflects a fundamental aspect of the law.
