Which types of cells are typically considered radioresistant?

• A. Skin cells
• B. Reproductive cells
• C. Nerve cells
• D. Bone marrow cells

Answer: (C)

Nerve cells, or neurons, are often considered radioresistant compared to other types of cells in the body. Radioresistance refers to the ability of certain cells to withstand exposure to radiation without experiencing significant damage or loss of function. Nerve cells are relatively non-dividing, which is an important factor in their radioresistance. Since radiation tends to have a greater effect on rapidly dividing cells, which are more susceptible to DNA damage and mutations, the slower turnover of nerve cells allows them to better resist radiation's harmful effects. This contrasts with cells like bone marrow cells, which are actively dividing and, therefore, more sensitive to radiation. The radioresistance of nerve cells plays a critical role in treatments involving radiation, as it affects how different tissues respond to radiation therapy, protecting critical functions associated with the nervous system. Understanding the characteristics of various cell types in relation to radiation exposure is vital for both treatment planning and safety protocols to minimize damage during procedures involving radiation.
