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.

Simple Activities to Understand Muscles
