Did you know that you had more bones when you were born than you have now? The skeletons of human babies have about 300 bones, but these soon fuse together as the baby grows and a human adult has only 206. This framework of bones supports our bodies - imagine if we had no skeleton, we'd be like bags of water! Our bones also allow us to move (think of the arm and leg bones) as well as protecting our organs. The skull is like a helmet which surrounds our brain, protecting it from knocks, and the breastbone and ribs form a protective cage around our heart and our lungs.

1 .

Which organ does the cranium protect?

The liver

The heart

The brain

The lungs

The cranium is another name for the skull

2 .

What does the spinal column contain?

Bones called invertebrates

One long, flexible bone

Two bones - a neck bone and a back bone

Many smaller bones called vertebrae

Vertebrae is a plural. One of them is called a vertebra

3 .

Skeletons aid movement in animals, but they can't move on their own. What else is needed?

Joints and muscles

Muscles and tendons

Tendons and cartilage

Cartilage and joints

Joints allow the skeleton to bend while muscles provide the power to move

4 .

Which device allows us to see bones inside a living animal?

A digital scanner

An X-ray or MRI machine

A photocopier

A microscope

If a doctor thinks you may have a broken bone you might have to have an X-ray

5 .

What is an invertebrate?

An animal whose skeleton is made of cartilage

An animal without a spine

An animal with a backbone

An animal without a skeleton

An invertebrate is an animal without a spine while a vertebrate has a spine

6 .

What is the function of the skeleton?

To protect vital organs

To allow movement

To support the body

All of the above

The skeleton protects vital organs, supports the body and allows it to move

7 .

Which of the following statements is not true?

Bones are living tissue

Exercise helps bones to become stronger

Good nutrition helps bones to become strong

Bones do not grow

Your skeleton grows just as the rest of your body does - can you imagine what would happen if a baby's bones never grew?

8 .

Which part of the human skeleton protects the heart?

The cranium

The scapula

The sternum

The clavicle

Another name for the sternum is the breastbone

9 .

What is an exoskeleton?

A weak skeleton

An external skeleton

A skeleton without joints

An internal skeleton

Humans and other mammals have an endoskeleton - an internal skeleton. An exoskeleton is the opposite - an external skeleton. Animals such as spiders, insects, crabs and lobsters have exoskeletons

10 .

What is another name for the clavicle?

Collarbone

Skull

Shoulder blade

Shin
