Biobeyond Unit 8: Lifting Tons and Skeletons - Questions and Answers, Exams of Biology

A series of questions and answers related to the effects of microgravity on the human skeletal system. It explores the concepts of bone density, osteoblasts, osteoclasts, and the impact of weightlessness on bone health. The document also discusses the importance of exercise in maintaining bone health in space. It is a valuable resource for understanding the challenges of space travel and the adaptations required for human survival in microgravity.

What do you think is a key difference between living on Earth and in space? Click on
the pictures to find out more. - Correct Answer-I think a key difference between living in
space and Earth is that there is a gravitational pull when on Earth, but not in space.

Reduced loading...more osteoclasts...dissolving bone Dissolving too much...weaker bones Why do you think bones such as the pelvis and femur lose the most density? - Correct Answer-They have constant stress on Earth so they produce more osteoblasts. Then in space, since those bones are not being used to hold themselves up there are a lot of osteoclasts dissolving the bones. Which of the following might be useful for you to institute to counteract this problem? - Correct Answer-exercising Which of the following are benefits of regular exercise? Select all that apply. - Correct Answer-all of them How do you think astronauts keep their balance while using such a device in microgravity? - Correct Answer-harnesses Summarize what you've learned in the form of a tweet to your crew mates. - Correct Answer-You need to use your bones.#spaceexercise
