How many bones does a human have?

When human beings are born, the skeleton consists of more than 300 bones or cartilages. By the time a person has grown up, the skeleton only has about 206 to 214 bones (depending on how you count the number can vary slightly), half of which are in the hands and feet. In the course of development, the bones partly grow together (e.g. skull, hand), become more stable and resilient and thus strengthen the human skeleton.

functions of the skeleton

The bones are connected by joints or joints and give the body shape and support. This gives the body its stability and offers the muscles a flexible framework for movement and activity. The second important function of the skeleton is the protection of the internal organs. For example, the heart and lungs lie securely in the chest.

In addition to these two central tasks, the bones also have another important task, namely the production of blood cells. Blood cells are made in the bone marrow, a mesh-like tissue with a high blood supply that fills the cavities inside the bones.

By the way …

  • Every human being has an  individual  skeleton – if you compare the skeletons of people of different stature, these clear differences show. And the number of bones can also vary, depending on how many smaller bones have grown together to form larger ones.
  • The  smallest  human bone is found in the ear. This is the stirrup in the inner ear, which, together with the hammer and anvil, is an important part of the auditory system.
  • The  longest  and  heaviest bone  in the human skeletal system is the thigh. It is about 50 cm long in an adult human who is 1.80 tall. The hamstrings are very sturdy because they have to support the entire body weight – when we stand, run or jump.
