Answer 10

The movement of a limb towards the midline of the body.

Question 11

Answer 11

When the bone at a joint moves around its own axis.

Question 12

What is weight bearing activity?

Answer 12

Activities that force your body to work against gravity. For example, walking, running and tennis.

Question 13

What is the benefit of weight bearing activities?

Answer 13

Weight bearing activities increase bone density; this helps to reduce the risk of osteoporosis as a person gets older.

Question 14

What are the 2 long term effects of exercise on the skeletal system?

Answer 14

Increased bone density and increased strength of ligaments and tendons.

Question 15

What are the 3 benefits of increased bone density?

Answer 15

Reduce the chance of osteoporosis, gives better posture and reduces the chance of fractures.

Question 16

What are the 2 benefits of stronger ligaments and tendons?

Answer 16

Better support of joints (more stability) and increased production of synovial fluid lubricates the joints aiding flexibility.

Question 17

What are the 5 different potential injuries that might occur in the skeletal system?

Answer 17

Fractures, Tennis and Golfer’s Elbow, Dislocation, Sprains and Torn Cartilage.

Question 18

What are the 4 different types of fracture?

Answer 18

Compound, Closed, Simple and Stress
