The backbone (vertebral column)

HintIt is made of many small bones.

The whyThe vertebrae have a hole through them where the spinal cord runs. The pads between them let the back bend.

Protection

HintThink of what a cage does for something soft inside it.

The whyThe ribs, skull and backbone guard soft organs: the ribs shield the heart and lungs, the skull the brain and the backbone the spinal cord.

Calcium

HintMilk gives you lots of it.

Answer in your head…What joins a muscle to a bone?

Tap to check

★ KS3-BIOL-HUM-0028Front

Biology · Human body systems, Year 7: more practiceProfessor Darwin

A tendon

HintIt is tough and does not stretch much.

The whyA tendon is a strong cord of tissue. When the muscle contracts it pulls on the bone through the tendon.

Answer in your head…Why must muscles work in pairs?

Tap to check

★ KS3-BIOL-HUM-0029Front

Biology · Human body systems, Year 7: more practiceProfessor Darwin

A muscle can only pull, so another muscle is needed to pull the bone back

HintMuscles cannot push.

The whyA muscle can only contract and pull. One muscle bends a joint and its partner straightens it again.

Answer in your head…The quadriceps muscle at the front of the thigh straightens the leg. Which muscle at the back of the thigh bends the knee?

Tap to check

★ KS3-BIOL-HUM-0030Front

Biology · Human body systems, Year 7: more practiceProfessor Darwin

The hamstring

HintIt is the muscle pair partner.

The whyThe quadriceps and hamstring form an antagonistic pair. When one contracts the other relaxes.

Answer in your head…What happens to the length of a muscle when it contracts?

Tap to check

★ KS3-BIOL-HUM-0031Front

Biology · Human body systems, Year 7: more practiceProfessor Darwin

It gets shorter (and fatter)

HintContract means to pull together.

The whyA muscle contracts and shortens, which pulls on the bone it is attached to.
