I ended up going to MIT to study neural interfaces. I was growing cardiac and neural tissue, and he was growing bone and cartilage. So this is certainly a team effort. As someone who is passionate about science, how would you encourage more women to enter the STEM science, technology, engineering and math fields? As little kids, we are all into science, but then we have to narrow our studies in our teen years.
That's when we start to lose our girls, but also many boys, so let's make sure we find ways for them to stay engaged. Toys are a great gateway, and there are some brilliant innovators in that field, like Ayah Bdeir of littleBits, and Debbie Sterling of GoldieBlox.
Remembering that learning is about play, and careers can also be about play, all those are ways of making sure we have a diverse set of contributors.

The secret to success is doing the right kind of exercises to stretch and strengthen the spine. Furthermore, special hands-on techniques performed by a physical therapist can improve your spinal movement and alignment.
Being taller can be as simple as improving your posture. This leads to many health benefits and the elimination of most neck and back aches. Find out how we can help you improve your posture and spinal mobility by calling and speaking to one of our physical therapists today. Bones change in their density all the time. Calcium is constantly being laid down and taken up by the bone cells on a daily basis. Bone growth is dependent on the amount of force and stress placed on the bones.
This is why astronauts who are weightless lose a substantial amount of their bone mass in just a couple of weeks. Here is what you can do to ensure your bones are healthy and strong:.
Of course, the best memories probably come from the thrilling rides that take your breath away. When you're little, though, you don't always get to ride the most exciting rides.
As you step up to the front of the roller coaster entrance, you're usually greeted by a sign indicating you have to be THIS tall to ride. If you're under that mark, you probably yearn for the day when you'll grow tall enough to ride. Most kids spend time when they're little dreaming about what life will be like when they grow bigger. Specifically, have you ever thought about how your bones grow?
When you were born, every part of you was tiny — even your bones! Babies are born with about bones. This is approximately more than the bones you'll have as a full-grown adult. So what happens? Do you lose some bones? Not at all! Many of the tiny bones you're born with fuse together over time to form bigger, longer bones as you mature. They also go through significant changes as they get bigger and grow into mature adult bones.
When babies are born, many of their bones are made partly or mostly of a soft, flexible substance called cartilage. Pinch the end of your nose and the top of your ear. Feel how they're soft and flexible? That's because those parts of your body are made of cartilage.
As you grow, the cartilage in your bones grows. Over time, it slowly gets replaced by bone with the help of calcium. This process is called ossification. During ossification, layer upon layer of calcium and phosphate salts begin to accumulate on cartilage cells.
Once encased in these minerals, the cartilage cells die, leaving tiny pockets behind. Blood vessels grow into these tiny pockets, delivering specialized cells called osteoblasts. The osteoblasts help to collect additional calcium and also produce a substance full of collagen fibers. Osteoblasts also produce layers of cortical bone that surround the cartilage. After making the cortical bone , osteoblasts become cells called osteocytes that work to form a sponge-like lattice of marrow and a substance called cancellous bone inside the developing bone.
Eventually, other cells known as osteoclasts make their way into the middle of developing bones. They use hydrolytic enzymes and acids to dissolve the cancellous bone and make room for more marrow. This process continues until all the cartilage has turned to bone. The process of ossification is usually complete by your mid-twenties. At that point, your bones are as big as they'll ever be. Although they won't continue to grow bigger, they can heal and repair themselves in the case of fractures.
Are you ready to keep growing? Be sure to check out the following activities with a friend or family member:. Sometimes, the privacy settings change and other times the videos are removed from the link we had.
But, we're making a note and will try to update the video soon, since it isn't working for us, either! Also, sometimes there are filters on a school system's Internet that doesn't allow videos from certain sites to play. In the future, if you see a video that won't play, just leave a comment so we can check into it!
It is a pretty amazing process, though, huh Connor? Thanks for reading about how bones grow! Hi, gabe! We're glad you liked this Wonder! Thanks for joining the discussion, Wonder Friend!
