Muscular System
 

A popular and traditional Halloween costume is that of a skeleton. Could a skeleton really walk by itself? What do you think? In the bone section of KidsBiology.com we learn that skeletons have the important job of providing our bodies with strength and form. The task of moving our bodies from one place to another belongs to another part of our bodies known as muscles. Without muscles we could not move.





Our bodies are made up of a variety of very large and very small muscles. From the powerful leg muscles that you use when you jump up and down to the tiny muscles that make your eyes blink, anytime you move, you are using muscles. In fact, as you read this article on our website you are using muscles to move your eyes back and forth. Scientists have estimated that about 40%, or almost half, of your body is muscle.

 
Many large and small muscles

 

What Are These Things We Call Muscles

There are three different types of muscles within your body. Each muscle type is different because it has a different type of job to do. Each muscle type is specialized to perform the important tasks that keep you alive. These three muscle types are Skeletal Muscles, Smooth Muscles, and Cardiac Muscles.
