Muscles
Key points :
Introduction to Muscles
- What Are Muscles?
- Muscles are soft tissues in our body that help us move.
- They are like stretchy rubber bands that can tighten and relax.
Types of Muscles

- Skeletal Muscles
- These muscles are attached to bones.
- They help us move our arms, legs, and other body parts.
- We can control these muscles by thinking about moving.
- Smooth Muscles
- These muscles are found in our stomach, intestines, and other organs.
- They work automatically without us thinking about it.
- Cardiac Muscle
- This muscle is found only in the heart.
- It works non-stop to pump blood throughout our body.
How Muscles Work
- Muscle Pairs
- Muscles usually work in pairs. When one muscle tightens, the other relaxes.
- For example, to bend our elbow, the muscle on the front of our arm tightens while the one on the back relaxes.
- Movement
- Muscles pull on bones to make them move.
- Different muscles work together to help us do activities like running, jumping, and playing.
Keeping Muscles Healthy
- Exercise
- Moving our bodies helps muscles stay strong.
- Activities like running, playing, and even walking help keep muscles healthy.
- Healthy Eating
- Eating foods like fruits, vegetables, and proteins helps muscles grow and stay strong.
- Drinking water is also important for muscle health.
Fun Facts About Muscles
- Number of Muscles
- Our body has more than 600 muscles.
- The smallest muscle is in the ear, and the biggest is in the buttocks (gluteus maximus).
- Involuntary Muscles
- Some muscles work without us thinking, like our heart muscle.
