Ask A Biologist: Busy Bones

We need our bones to walk, run, jump and move, but this is not all they do.

Bones are very busy even when you are sleeping at night. They are where blood cells are made and store most of your body’s calcium. Bones are also very good at repairing themselves.

Bone Lab

In this lab you can explore the bones of the human skeleton using our skeleton viewer that can also be played as a game. You can also cut and peel apart a bone to look inside. For a closer look at bones you can use the virtual microscope to inspect their tiniest details.

Bone Basics and Bone Anatomy

Have you ever seen fossil remains of dinosaur and ancient human bones in textbooks, television, or in person at a museum? It’s easy to look at these and think of bones as dry, dead sticks in your body, but this couldn’t be further from the truth. Bones are made of active, living cells that are busy growing, repairing themselves, and communicating with other parts of the body. Lets take a closer look at what your bones do and how they do it.

Experiments

Bones need to be both strong and flexible in order to do their job. Bones that are strong but not flexible will be brittle and easily broken. However, if bones are flexible but not strong, they would not support the weight of your body or the stress from your muscles pulling on them. Try these neat experiments to see what happens when bones lose their strength or flexibility.

How Do Bones Heal?

What’s happening inside your body when a bone is broken? Lets take a closer look at the step-by-step process your body goes through to heal a broken bone. You can begin by watching this short video that shows the different stages of bone healing. If you want learn more about bone repair we have included details of each step below the video.
