Which of the following cell types are at least sensitive to ionizing radiation damage?
All of the following cell types can be sensitive to ionizing radiation damage: Stem cells: can be more sensitive because they are actively dividing. Rapidly dividing cells: such as those in the skin, digestive tract, and bone marrow. Cancer cells: due to their increased rate of cell division compared to normal cells.
What cell types are most sensitive to ionizing radiation damage?
Cells that rapidly divide are most sensitive to ionizing radiation damage, including stem cells, progenitor cells, and cells of the gastrointestinal tract, bone marrow, and skin. These cells have higher metabolic activity and are less able to repair damaged DNA compared to more differentiated cells.
Which of the cell types are most sensitive to radiation damage?
Rapidly dividing cells like stem cells, bone marrow cells, and intestinal cells are most sensitive to radiation damage due to their high rate of cell division, making them more susceptible to DNA damage. Cells in the skin and mucous membranes are also highly sensitive to radiation.
Which cell type is least sensitive to ionizing radiationcells that don't have nucleus cells that are activiely dividing cells that divide slowly or cells that don't divide?
Cells that don't have a nucleus, such as red blood cells, are generally the least sensitive to ionizing radiation. This is because they lack the DNA that is typically damaged by radiation. In contrast, actively dividing cells and those that divide slowly are more sensitive due to their higher levels of DNA synthesis and repair processes. Cells that don’t divide at all are also less sensitive, but not as much as anucleated cells.
Why do many radiation therapy patients have low red blood cell counts?
Bone marrow cells divide rapidly and are susceptible to the effects of radiation.
what cells types are least sensitive to ionizing radiation damage?
Cells that do not have a nucleus
What types of cells are most sensitive to radiation damage?
Rapidly dividing cells, such as those in the bone marrow, gastrointestinal tract, and hair follicles, are the most sensitive to radiation damage. These cells are actively undergoing mitosis and are therefore more susceptible to the effects of radiation.
What type of cells are least sensitive to radiation exposure?
Cells that are least sensitive to radiation exposure are typically those that are in a more differentiated state and have a lower rate of division. This includes mature nerve cells, muscle cells, and certain types of bone cells. These cells are less likely to be affected by radiation because they are not actively proliferating and have more robust repair mechanisms compared to rapidly dividing cells, such as those found in the bone marrow or gastrointestinal tract.
Which cell types are most sensitive to ionizing radiation?
Rapidly dividing cells, such as those found in the bone marrow, gastrointestinal tract, and hair follicles, are most sensitive to ionizing radiation due to their high rate of proliferation. This is because ionizing radiation primarily affects cells during the division process, when the DNA is most vulnerable to damage.
23) Which of the following cell types are least sensitive to ionizing radiation damage?
Mature red blood cells are least sensitive to ionizing radiation damage because they do not possess a nucleus, limiting their ability to repair DNA damage caused by radiation exposure. This makes them less vulnerable to the harmful effects of ionizing radiation compared to other cell types like stem cells or rapidly dividing cells.
What cell types are most sensitive to radiation damage?
The ones with the shortest (normal) lifespans - like skin & the lining of the gut.
Cell types are most sensitive to radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
