Structure of a Human Skeleton
The human skeleton works as a framework for the body by supporting tissues. It also protects internal organs for our body. There are a total of 206 bones in the human body. Its main functions are to give a proper shape to your body, provide attachment for muscles and to produce red blood cells. It consists of many individual bones and cartilages.
Facts you didn’t know: –
- Many bones fuse together as you grow. This is the reason why you are born with about 300 bones and end up with just 206.
- The hands and feet contain over half of the body’s bones. As each hand has 27 bones and each foot has 26 bones.
- Most adults have 24 ribs but a few people have an extra rib, called a cervical rib, just above the collarbone. It can cause health issues.
- Ancient Egyptians were the first to develop the world’s first functional prosthetic bone.
- The cells of human bones are susceptible to tumors and cancer as human bones are made of living, active cells.
- Human bones are stronger than steel. The strongest bone is the femur, it is also the longest bone in our body.
- The collagen in human bones gets replenished constantly, so every 7 years you have a new skeleton.
- The so called ‘funny bone’ is not a bone actually. It is your ulnar nerve that runs inside your elbow.
- Human skull consists of 22 separate bones.
- Osteoporosis is a disease in which the bones become fragile and prone to fracture.
- Your joints start to creak when cartilage wears out as it helps to cushion the joints.
- Your teeth are part of your skeleton too. They are made of calcium and minerals like your bones but they are not as flexible as bones because they lack collagen.
