5

What are long bones?

They allow large movements, like kicking a football.

6

What are short bones?

Bones that allow more controlled movements, like pointing you toes in a gymnastics routine.

7

What is a flat bone?

Bones that protect vital bones in the body, such as the brain, the heart and the the lungs.

8

What are irregular bones?

Irregular bones have specific functions, like the vertebrae protects the nerves that runs down the spine.

9

What are the 5 functions of the skeleton?

Protection
Blood Production
Support
Movement
Store

10

How does the skeleton protect you?

It protects our internal organs from damage, like the ribs protect our lungs and heart.

11

How does blood production help you?

Red and white blood cells are made here along with platelets, to help the body function properly.

12

How does movement of the skeleton help you?

Without it we would be unable to move at all, as the skeleton provides an attachment point for muscles.

13

What does supports do for you?

It’s provides support for muscles and vital organs.

14

What does storage in the skeleton do for us?

It stores minerals like calcium and iron, which helps the body function properly and the bones to maintain strength.

15

Where is the hinge joint?

Knee
Elbow

16

Where is the ball and socket joint?

Shoulder
Hip

17

Where is the gliding joint?

Feet
Hands

18

Where is the pivot joint?

Neck.

19

Where is the condyloid joint?

Wrist.

20

Where is the saddle joint?

Thumb.

21

What does cartilage do at the joints?

It prevents bones from rubbing together, like a cushion.

22

What does the joint capsule do?

Two layers of membrane that surrounds the joint and keeps everything in place.

23

What does the synovial membrane do?

Releases synovial fluid.

24

What is synovial fluid?

A slippery liquid which lubricates the joint and stops the bones rubbing together.

25

What do ligaments do?

Attaches bone to bone.

26

What is flexion movement?

Reducing the angle at a joint, for example bending the knee back before kicking a football.

27

What is extension movement?

Increasing the angle at a joint, for example when a performers straightened their leg to kick a football.

28

What is adduction movement?

Moving the body part towards the centre of the body, for example, when a netball player brings there arm in to catch a chest pass.

29

What is abduction movement?

Moving the body part away from the centre of the body, like the outward pull of the arm when swimming breaststroke.

30

What is rotation movement?

Turning or twisting a body part, for example the rotation of the shoulder when throwing a cricket ball.

31

What is plantarflexion?

Flexion at the ankle so the foot points more inferiorly, for example on point in ballet.

32

What is dorsiflexion?

Extension at the ankle so the foot points more superiorly, for example, going over a hurdle.
