FUNNY BONES!

What are bones made of?

The most amazing thing about our bones is that they are extremely STRONG for their lightness in weight! They’re not as dense as steel or heavy as iron because they need to be lighter. Imagine trying to walk up a set up stairs if your bones were made of iron? No way! Our bones may be light in weight – but they are as strong as concrete.

The Mystery Inside Our Bones! 

 What’s most interesting about our bones is what lies beneath them. If we were to look inside our bones, the first part we would notice would be the Periosteuma thin, dense membrane outer cover that contains nerves and blood vessels and nourishes the skeleton – also known as the Compact bone.  Beneath your skeleton is the  “Cancellous,” a super strong, sponge-like surface that protects the bone marrow beneath it. Our bone marrow is sort of like a thick jelly, and its job is to make our blood cells. There are two types of marrow: red and yellow. Red marrow is where all new red blood cells, white blood cells, and platelets are made. The bones that make up your skeleton are all very much alive, growing and changing all the time like other parts of your body. Baby’s are born with 300 bones. Many of these bones are called “Cartilage.” Cartilage is soft and flexible when you’re a baby but as you grow, the cartilage is replaced by bone. Eventually some of those bones fuse together, and by the time you reach adolescence, you’ll have 206 bones.

What can I eat to help make my bones strong?

Bones love Calcium! My favorites are milk, yogurt, cheese, orange juice, leafy and greens and sardines! Another way to keep your bones super strong is by getting plenty of exercise and making sure that you protect them when you play sports! This last thing you need is a broken bone!  You should always protect your skull bone by wearing a helmet when you are on a bike. It’s also a good idea to shield your elbows and knees by wearing  guards when you’re skating or riding a scooter. Speaking of bones – I better protect mine. I think I’ll have some frozen yogurt!
