• tendon

• ligament

Multiple Choice

Look at the image, what is the effect of this on the part of the body?

Explain how muscle perform movements

Multiple Choice

Where do muscles get the impulses to move the body?

• from the nerves

• from the brain

• from the muscles itself

• from the bones.

Multiple Choice

When muscles contract, what is most likely to happen?

• The muscle shortens and pushes the bone

• The muscle shortens and pulls on the bone

• The muscles lengthens and pushes the bone

• The muscles lengthens and pulls on the bone

Multiple Choice

What explains why muscles work in pairs?

• The joint needs both muscles to pull the bone in one direction.

• The joint needs both muscles to push the bone in one direction.

• The joint needs one muscle to pull the bone in one direction and the other muscle to pull it to the opposite direction.

• The joint needs one muscle to push the bone in one direction and the other muscle to push it to the opposite direction.
