Today, we’ve been learning all about muscles.
Background: Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. Then, when the movement is completed, the flexor relaxes and the extensor contracts to extend or straighten the limb at the same joint.
We made some videos about the movement that happens and the muscles that work. Check them out below:
