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.

YEs I have been bullied. A lot. People who I think are my friends are back stabbers. They suddenly just like turn on me. I've had rumours spread about me and I was so sad. I hated being bullied. But the best thing to do if you are being bullied is to hold your head high and not cry. Because if you show a single tear that is what the bully wants And it will take you as an easy target and will bully you more and more and more and more. And bullies won't stop until you stand up to them.

I would also talk to them and tell them how you feel. If they still say they are signing you up for the membership as a 13 year old and it scares you that much I would just tell them to leave you off the membership until you do turn 13.

I think every house has some drama going on in it everyday. In my house my Mom is a divorced mother of 3 kids. My older sister is away at college but when she was here there were yelling matches between my mom and her about staying out too late and getting a speeding ticket. Also with my mom being the only one raising us she has to work full time leaving me to watch my little brother who is 10 after he gets home from school. There also can be some battles that go on there and my mom doesn't want to here it from me or him when she walks through the door after work. I just try to not make it all personal and chalk it up to the stress of everyday life.
