Structure of a Human Skeleton
Human skeleton works as a framework for the body by supporting tissues. It also protects internal organs of the human body. There are a total of 206 bones in the human body. Its main functions are to give 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 of the 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 one to develop 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 collagen in human bones gets replenished constantly so in 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 them.
- 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.
