[Financial News] The bone structures of young children and adults are completely different. This is due to the differences in their stages of growth, and young children also have considerably more bones than adults.
According to the science YouTube channel Science View on the 29th, children's bodies are completely different from those of adults. In fact, an X-ray of a young child's hand shows that all the finger bones are separated. This is because the child is still growing, unlike adults, whose finger bones have all joined together.
As a result, while the adult body consists of just over 200 bones, a young child's body has around 300 bones.
Young children also have an anterior fontanelle, commonly known as a soft spot, in their skulls. This is also because their skulls are still growing. As they gradually grow, the skull becomes harder and the anterior fontanelle disappears. The anterior fontanelle can remain until a person's late 30s. In other words, the skull is somewhat divided to allow it to grow, and as a person reaches adulthood, it grows together and the anterior fontanelle disappears.
The shape of the spine also differs between adults and young children. Adults have an S-shaped spine to support their weight effectively. Young children, on the other hand, have a spine curved in a C shape. The spine has a different form because it is also still developing.
