Kids Learning → Human Body → Muscles → What is Muscles

Overview

Muscles are special tissues in our bodies that help us move. They work by contracting and relaxing, which means they get shorter and longer. There are three types of muscles: skeletal, smooth, and cardiac. Skeletal muscles help us move our arms and legs, smooth muscles help our organs work, and cardiac muscles make our hearts beat. Understanding muscles helps us learn how our bodies function and stay healthy.
