Skeleton Description and Functions
The skeleton is the framework of your body so it protects your body's most important organs. For instance; the skull protects the brain and the vertebrae protects your spinal cord. There are about 300 bones in a infants body. When you get older you have 206 bones because some bones fuse together to form a bigger bone. Bones also support all of your body and organs so if you didn't have any bones, you would be a glop of goo on the floor. The skeleton also has many functions. They are movement, support, protection, storage, and production of red blood cells. Joints are also very important to the skeleton too. Joints stay together because cartilage and ligament surrounds the joint and keeps it together but not to tight that the joint can't move. The most common and most used joint is the ball-and-socket joint. It it used in the shoulder, ball of the femur, and the hip. There is also the hinge joint which is an example of the fingers and toes and gliding joints which is an example of your vertebrae.



Fun Facts-
- The smallest bone in the body is the stirrup bone. The stirrup bone is located in your ear. It is surprisingly only 0.30 cm. long!

- The biggest bone in the body is the femur which is located at the thigh part of your leg. It can reach over 19 inches long!

- The most important bone in your body is your skull. Without it, your brain would get damaged and it could not send messages to the rest of your body. For instance, to move your arm you need the brain to send messages to tell your arm to move it.
