Why Do Tendons Connect Muscle to Bone?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do tendons connect muscle to bone?

The Big Idea

Tendons connect muscle to bone because a muscle needs a strong cable to pull on the skeleton! Without tendons, a muscle's squeeze would not move your bones at all. A tendon works like a power cord that passes the pull along.

Muscle Squeezes

Step one: the muscle squeezes. When your brain sends a signal, a muscle gets shorter and pulls. But a muscle is soft, so it needs something tough to pull with.

Tendon Pulls

Step two: the tendon pulls. Tendons are tough, rope-like cords that join the muscle to a bone. They carry the pull from the muscle across to the bone, with hardly any stretch.

Bone Moves

Step three: the bone moves. The bone swings, and you wave, kick, or jump. No tendons would mean no moves, because the muscle squeeze would not reach the skeleton.

A Closer Look

Let's take a closer look! The muscle is the soft, squeezy part. The tendon is a tough cable at its end. It hooks onto the bone and tugs it. One of the biggest is the Achilles tendon behind your ankle.

Quick Facts

Quick facts! A tendon works like a power cord that sends the pull along. The Achilles tendon is the thickest tendon in the body. It connects your calf muscle to your heel bone. Warm up before sports to keep your tendons happy.

Think Like a Scientist

Now, think like a scientist! Gently feel the Achilles tendon on the back of your ankle. Then rise up onto your toes slowly and feel it tighten. Tell someone what you felt!
