A muscle is a part of the body that makes us move.

This picture shows the muscles covering the human skeleton.

A muscle is a part of the body that can get shorter or longer to allow us to move about.

In a human the muscles are attached to bones in the skeleton.

Muscles can relax which means get longer or that can contract which means they get shorter.

When we exercise it makes our muscles bigger and stronger.

Muscles are organs in the muscular system which allow us to move.

Most muscles come in antagonistic pairs. This means when one contracts the other must relax.


When a muscle contracts it is called the 'agonist' and when it relaxes it is called the 'antagonist'.
