Question 14

3 systems of the skeleton

Answer 14

1. Protection
2. Support
3. Movement

Question 15

Protection of the skeleton

Answer 15

• protects internal organs

Example:
skull - brain
pelvis - reproductive organs

Question 16

Support of the skeleton

Answer 16

• without bones, we will become like jelly

- unable to move

Question 17

Movement of the skeleton

Answer 17

• joints

- provides a base for muscles to attach to

Question 18

(1) Pelvis
(2) Ribcage
(3) Skull
(4) Ribcage
(5) Spine

Answer 18

(1) Pelvis - Reproductive organs
(2) Ribcage - Heart
(3) Skull - Brain
(4) Ribcage - Lung
(5) Spine - Spinal cord

Question 19

What are joints?

Answer 19

Where 2 bones meet

Question 20

Hinge Joints

Answer 20

• the movement of 180°
• works like a lever
• contracts and relaxes (muscles) to move the joint

Examples:

• Elbow
• Knee
• Wrist
• Ankle

Question 21

-

Question 24

What muscles are the Bicep and triceps?

Answer 24

Antagonistic muscles

Question 25

Tendon

Answer 25

- They connect muscle to bone - They are stiff - If they were stretchy the joint wouldn't move - Tendons have to be tough to hold powerful muscles to strong bones

Question 26

Cartilage

Answer 26

- Made out of Strong & Spongy tissues - Formed at the end of the ball & socket, hinge & pivot joint - the ends of the bones grind together when you have arthritis

Question 27

Ligament

Answer 27

- Stretchy - They connect bone to bone - They would snap every time we bend a joint

Question 28

Synovial Fluid

Answer 28

- found between the ends of bones in joints - synovial fluid makes the joints smooth and friction-free - it is important during exercise because there is a lot of pressure put onto our joints
