Let's keep learning about the muscles in the human body!
Last time we learned about how the Forearm flexors are used to help flex your elbow together.
Even though the forearm muscles are smaller than biceps, there are a few other important muscles there too.
The extensor muscles are the ones you use when you move the back of your hand up toward your forearm,
or when you open up your hand and spread out your fingers.
