1

What is the musculo-skeletal system made up of?

Muscles and bones

2

Name the 5 functions of the skeleton

1. Protection of vital organs
2. Muscle attachment
3. Joints for movement
4. Platelet, red and white blood cell production
5. Storage of calcium and phosphorus

3

How does the skeleton protect vital organs in sport?

The hard bones of the skeleton protect vital organs from being damaged. For example if a ball hits a person's chest the ribs protect the heart and lungs

4

Give two examples of bones that protect vital organs

Cranium protects the brain
Ribs protect the heart and lungs

5

Why is it important the skeleton allows muscle attachment?

Muscles need to attach to bones (via tendons) so that when they contract movement can occur

6

How does the skeleton's function of 'joints for movement' aide a sports performer?

Where two bones meet a joint is formed.
When the muscle attached to the bones (via a tendon) contracts it pulls on the bones. Where the bones form the join, movement occurs.

7

Why is it important for a person to have a good store of calcium and phosphorus?

Both these minerals help to keep bones strong and healthy. Strong and healthy bones are needed for exercise.

8

Red blood cells are needed for...

Carrying oxygen around the body

9

White blood cells are needed for...

Helping the body fight infection

10

Platelets are needed for...

Clotting the blood. It is platelets that form a scab when you cut yourself

11

There are 4 different classification of bones. What are they?

1. Long
2. Short
3. Flat
4. Irregular

12

What is the main characteristic of a long bone?

Longer than they are wide

13

What is the main characteristic of a short bone?

Roughly the same size in length, width and thickness

14

What is the main characteristic of a flat bone?

Thin and flat

15

What is the main characteristic of an irregular bone?

Oddly shaped

16

What is the main function of a long bone in sport?

Acts as a lever to create movement

17

What is the main function of a short bone in sport?

Weight bearing and shock absorbing

18

What is the main function of a flat bone?

Muscle attachment
Provide protection

19

What is the main function of an irregular bone?

Provide protection
Specific function - vertebrae allow head to nod and rotate

20

Name three long bones

Femur
Phalanges
Humerus
Ulna
Radius
Tibia
Fibula

21

Name two short bones

Carpals (wrist)
Tarsals (foot)

22

Name three flat bones

Cranium
Patella
Scapula
Sternum
Clavicle

23

Name the main group of irregular bones

Vertebrae

24

How many bones is the vertebral column consist of?

33

25

How many bones are in the cervical region of the vertebral column?

7

26

How many bones are in the thoracic region of the vertebral column?

12

27

How many bones are in the lumbar region of the vertebral column?

5

28

How many bones are in the sacrum?

5

29

How many bones make up the coccyx

4

30

What is the function of the cervical region of the vertebral column?

It is the neck and allows a range of different movements such as looking side to side and up and down
