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. Theyre 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.

Two years ago my parents broke up. I was never really the same after that point. My mother she began to just not care about anything. She would go out clubbing every Friday and would yell at me for my attitude towards it. Why would I be okay with her doing that??? I didn't really realise it but I began feeling kind of depressed. Of course we didn't fight all the time but when we did I would always end up crying alone in my room. And it would be really painful. One time I cried every night for a week because of her. A week ago, I felt really sick at school so I went to the sick bay but my Mum refused to believe I was sick. She thought I was lying and being over dramatic as usual. I felt really horrible after that, that the teacher sent me to the guidance councellor and almost immediately I burst into tears. I didn't even know why I did but the councellor did a little test on me and came to the conclusion I was slightly depressed and had anxiety. It wasn't really surprising but hearing it out loud just felt really weird. Even after knowing that fact my mother doesn't really act any different. She's not a bad person I swear but she can just be really horrible at times. Anyways, that's technically whats been happening in my life lol. Nothing really interesting

theres this guy that i really REALLY like, im not sure if he likes me back. i put my mobile # on a piece of paper and slipped it in his locker, he hasn't texted or called me yet. Today at lunch i asked his friend to ask if he likes anyone but his friend keeps lying to me and won't tell me if he said anything. The guy and I were best friends in 5th grade but now that we're in different classes we don't talk much anymore. My friends said that i have a chance with him and that we have a lot in common, but im pretty sure he likes this other girl but im also pretty sure he likes me. I want to make a move but i don't wanna end our friendship i don't know what to do.

It's good to have both to talk too about things. But, what's the point of being with someone if you can't trust them enough to even tell them things?
