Explanation:
Detailed explanation-1: -Those nerves and muscle cells are the slowest to regenerate and are the least sensitive cells to Radiation.
Detailed explanation-2: -The least sensitive are nerve cells and muscle fibers.
Detailed explanation-3: -Rapidly proliferating non-differentiated cells are the most radiosensitive. Well known representatives of this class of cells are the stem cells of the hematopoietic tissues and the cells of the intestinal crypts.
Detailed explanation-4: -Adult skeletal muscle is considered resistant to ionizing radiation unless higher doses of radia-tion are applied; a fact that is attributed to the low number of radiosensitive proliferating cells in adulthood.
