MUSCLES (AND BICEPS AND TRICEPS) WITH 100% CORRECT ANSWERS
Muscles work by getting shorter - what is this process called? - answer Contraction.
What attaches the muscles to the bones? - answer Strong tendons, and so when a muscle contracts, it pulls on the bone, and the bone can move if it is part of a joint.
What are antagonistic muscles and why are they needed? - answer Antagonistic muscles are a pair of muscles. Muscles can only pull and cannot push and so this would be a problem if a joint was controlled by just one muscle as when the muscle had contracted and pulled on a bone there would be no way to move the bone back again.
What is an example of a pair of antagonistic muscles and how do they work? - answer The biceps and triceps. When the biceps muscle contracts, the forearm moves up and the triceps relax, then when the triceps muscle contracts, the forearm moves down and the biceps relax.
