Reduced Gravity - The Effects on the Human Body Post-Conference Assessment Quiz - Here is how you did.

Question 1. - What is Microgravity? Question 1 Answer: The term, microgravity literally means small gravity, from the roots mikros (Greek) small + gravity. A reduced gravity environment (or g), is defined as any environment where gravity levels are significantly reduced compared to those we experience at Earth's surface. We refer to Earth's surface environment as a one-gravity (1-g) environment.

Question 2. - Reduced gravity is simulated on Earth by NASA with: Question 2 Answer: All the above.

Question 3. - Bone loss and muscle atrophy are effects of reduced gravity on the human body. Question 3 Answer: True

Question 4. - How does fluid shift affect astronauts? Question 4 Answer: Fluid shift refers to the shift of fluids from the lower to the upper body upon exposure to, or recovery from, reduced gravity. As astronauts experience free fall, the fluids shift to the upper part of the body and astronauts have puffy heads.

Question 5. - Reduced gravity has no effect on the cardiovascular system. Question 5 Answer: False

Question 6. - List countermeasures to the effects of reduced gravity on the human body. Question 6 Answer: Exercise, Medications, Pre-Flight Training, Proper Nutrition.

Question 7. - How is the skeletal system affected by reduced gravity? Question 7 Answer: Loss of bone density.
