Questions and Answers

What is the function of the skeletal system in the body?

To aid in digestion, absorb nutrients, and eliminate waste

To generate heat, regulate body temperature, and produce hormones

To facilitate nerve transmission and control body movements

To provide support, allow movement, make blood cells, provide organ protection, and store minerals (correct)

Why are the highest pressures in the body found in weight-bearing bones and joints?

Because weight-bearing bones have a higher density compared to other bones

As a result of high levels of calcium and phosphorus in these bones

Because weight-bearing bones have more nerve endings

Due to high values of initial force and small areas to which this force is applied (correct)

How does the surface area of a bone at the joint contribute to pressure reduction?

By enhancing blood circulation around the joint

By distributing the force and reducing the pressure according to the equation P= F/A (correct)

By increasing the density of the bone tissue

By promoting nerve signal transmission in the joint
