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.

Hii, i want to give advice to all of you about this subject. first of all, always trust your BFF. why?, it's because she/he is the one who makes you feel like a family and always be there with you. Second, always remember your BFF where ever you are. i got this idea from my bff whose not n the same school with me. 8 February was her birthday while i said happy birthday to her 2 day later (i know i'm the worst). i literally panicked and said sorry to her like a thousand times. while she said "it's okay, i'm glad someone in your school (because some of us transfers here at my new school too) remembers my birthday, maybe all of them already forget me" she answered (which i'm touched). and the last, never ever betray your BFF. like i said at the start, they are like your family and will do anything for you to be happy. so keep their trust too. and that's all from me, hope it's helpful. love ya [s:sm3/1jw1]
