What is the muscular system?

The muscular system is a group of muscles in our body that helps us move and do things like running, jumping, and even smiling.

There are more than 600 muscles in our body!

Muscles are made of fibers that can contract and relax, which is what helps them move our bones and other body parts.

Without our muscular system, we wouldn’t be able to do all the amazing things we can do!
