SOC 12 - Skeletal System

Question 1

Long bones

Answer 1

generate movement (leavers)/ strength

Question 2

Short bones

Answer 2

weight-bearing

Question 3

Irregular

Answer 3

protection/ generate movement

Question 4

Flat bones

Answer 4

protect vital organs/ muscle attachment

Question 5

5 functions of the skeletal system

Answer 5

Protection of vital organs
Muscle attachment
Joints for movement
Storing calcium and phosphorus
Red and white blood cell production

Question 6

What is the skeletal system?

Answer 6

Includes all bones and joints in body. Each bone is a complex living organ made up of many cells, protein fibres, and minerals

Question 7

How does skeletal system protect vital organs?

Answer 7

Staying safe is important in sport and the skeleton play a key role. E.g. the skull protects the brain and the ribs protect the internal organs, including the heart.

Question 8

How does skeletal system allow for movement (joints)?

Answer 8

Joints allow the body to make a variety of movements. Some are small movements, like getting a grip of a javelin and larger ones, such as throwing a javelin.

Question 9

How does the skeletal system allow for muscle attachment?

Answer 9

The muscles you use in sport need strong points to attach to and bones provide that framework.
Muscles are attached to bones by tendons.

Question 9

How does skeletal system allow for storage of calcium and phosphorus?

Answer 9

The bones act as a store for calcium and phosphorus, two minerals that are vital for developing and maintaining the strong and healthy bones you need for exercise. The best sources for both minerals are milk, cheese and yoghurt. Phosphorus helps to reduce muscle pain after exercise.

Question 10

How does skeletal system allow for red and white blood cell production?

Answer 10

When the oxygen content drops, or the number or red blood cells goes down, your bone marrow makes more red blood cells; if you have an infection, it makes more white blood cells.
