Question 15

Trabecular bone at the ends of long bones houses red marrow and decreases the weight of the skeletal system.

Question 16

Vertebral bodies are specifically engineered to bear the summed weight of the body superior to them.

Question 17

Obese people induce more strain simply by equal daily activity as compared with their lighter peers.

Question 18

To achieve minimal essential strain (MES) in a young, active population, less rigorous exercise may be required to stimulate an increase in bone density.

Question 19

Bone mineral density is an indicator of long-term bone (skeletal) health. It is generally accepted that those who achieve good bone mineral density are less at risk for having an osteoporotic fracture later in life.

Question 20
