You probably think of death when you think about skeletons. Maybe you think that skeletons are like scaffolding, holding everything in the body in place. The truth is bones are a lot more. They're alive.

You probably think of death when you think about skeletons. Or maybe you think that skeletons are like scaffolding, holding everything in the body in place, and the bones are like metal bars. True but bones are also very much alive. They aren't just some solid material like metal, they are alive with cells. Human bones have three layers. The smooth, hard outer layer is cortical bone. Beneath this layer are many layers of cancellous bone. Cancellous bone looks kinda like a sponge. Although not quite as hard as cortical bone, it's still pretty strong. The third and innermost layer is the bone marrow. Bone marrow is like a thick jelly, and its job is to produce blood cells. So, as you can see, bones aren't only alive, they're responsible for keeping you alive as much as the heart or the brain!

What Do Bones Do?

1Bones make blood cells.

1Bones are the framework for your body.

How Many Bones?

Humans are born with 300 bones, but adults only have 206 bones. So what gives? Some of the 300 original bones in a baby are made of regular bone and some are made of a material called cartilage. Cartilage is soft and flexible to start, but over the years the cartilage grows and slowly hardens into bone. Also, some bones fuse together. All of this is part of the normal growth process.

Some time between the ages of 17 and 21, this growth process ends and your bones are as big as they're going to get. And like magic, you end up with 94 fewer bones than you started with.

Bits of Bones

1More than half of the body's 206 bones are in the hands and feet.

1The skull is composed of 30 different bones.

1The smallest bone in the body is the stirrup bone inside the eardrum. It is less an inch long.

1The largest bone in the body is the femur which is the leg bone that runs from the hip to the top of the kneecap (patella.)

1Everyone's heard of the funny bone, but did you know that humerus is the real name of the long bone that runs from your elbow to your shoulder.

I'm not quiet sure what's a real friend and what's a fake one anymore. I know when there's a friend who's only a school friend rather than an 'outside' friend as well, but at the same time it makes me so confused. Here's my story: There's a girl named Xian. We had a unique way of becoming friends ... but it clicked. For the whole year I've been trying to keep in contact with her ... but she's not very willing to try and put in any effort to stay in contact with me. Her personality is beyond sweet, and her skills at art are even better. If she was to have an award, it would be a giant trophy with her face plastered on it and big bold letters listing 'Nicest Girl In The World!' ... Its just ... she lied to me.  I was all about this friendship. I was ... i'll admit ... sort of a lost puppy following around her owner.  So, I got her this T-Shirt she really wanted for her birthday, and not long her birthday was mine, April First. I was expecting at least a letter, or maybe even something cheap. It didn't really matter to me.  But on my birthday she didn't even come to school. Nor when she got back did she ever say sorry, or give me any be-lated gift of any sort.  That should have been my first clue. Even my mother started catching on. My second clue was she even told me she was oblivious and wasn't good at keeping in contact. I thought she was joking. How could a friendship so sweet be tossed out just like that? My third one was near the end of school, one of her friends in elementary was bragging about the plushies she got from Xian. Apparently she had four from her.  Xian had originally told me it was AGAINST her religion to give out gifts to other people. I knew she wasn't lying about her religion in general, because I met her mom on a field trip and she was quiet ... different. But I didn't understand why Xian had gotten so many small plushies for her, and yet not a single small stamp for me? My last clue was the last day of school. She didn't even try to say good-bye or even hang out with me for that matter. I know what you're thinking. "Girl, you've gotta be kidding me if you can't see that she has no intention of being your friend!" But this girl was the nicest to me. She stood next to me during harsh times, and comforted me when I was down. She told me I was important.  And you don't get many friends to do those special things to you. It was rare to have a friend make me feel so tall and worthy.  ... So ... I can't understand ... why'd she do all that .... and suddenly ... just ... walk away ...
