Human Skeleton


The human skeleton is made up of bones. An adult skeleton consists of 206 bones. Our skeleton acts as an internal framework and its bones help muscles to act as levers to move the legs, arms and other body parts. We could no longer move our body without bones. In fact, you will look like a huge blob of jelly, without the skeleton.

What does our skeleton do?

Our skeleton helps us in many ways as follows;

  1. Our skeleton provides shape and support to the body.
  2. It protects the internal organs such as the brain, the heart, and the lungs and keep them in their proper place.
  3. It helps us to move as our muscles are attached to our bones.
  4. Bones in the skeleton help producing blood cells.

The Shinbone and the Calf Bone

These are the two long bones in the leg below the knee. The shinbone, also known as the tibia, is the ber and the larger of the two bones. It connects the knee with the ankle bones. The calf bone, also known as the fibula, is the smaller of the two bones and the thinnest of all the long bones.
