What You Need To Know About The Bone Structure Of A Child

The most interesting part of a human body is the human skeleton. Humans are a wonderful creature and the bone structure of a human body is even more exciting. At around the age of 21, the mass density of bones in the human skeleton reaches its maximum level. We can divide the human skeleton into two sections such as axial skeleton and appendicular skeleton. The axial skeleton comprises of verticals column, rib cage, and skull. Shoulder girdle, pelvic girdle and the bones of upper and lower limbs form the appendicular skeleton. There are few differences in the skeleton of an adult and a baby.

As we know babies have 270 bones and with times they get fused and the number decreases to 206. At the age of 25 the bones stop growing together as the growth is naturally complete. So naturally the interest in the child’s skeleton is much higher as they have more varieties and there are lots of things to know. When a baby is born, most of the bones start as cartilage and as the baby ages it gets more harden. The cartilage structures slowly ossify and some of the materials are changed.

As we are so interested to know more about the baby bone structures a very common question is frequently asked. Do baby have kneecaps? Well in order to answer this question we have to take the same reference of that cartilage. This is a very confusing question actually. As an adult, we have the patella that is the kneecap which is a flat circular bone in front of the bottom end of our femur. This patella actually helps to the extent our knees. But as a baby they also have patella but that is not made of bones. That is actually made of cartilage. In the process of ossification, that cartilage will actually become a bone. At the age of 3, this ossification of human knee starts.

The scientific reason behind this is still unknown. According to some doctors having a hard kneecap that is having bone in the patella can actually create a problem in crawling for babies. As with hard kneecaps while crawling it hurts too much. So maybe the lack of hard kneecaps is a blessing in disguise. There are lots of other things like this in human body and skeleton which can’t be described scientifically and the researches are in progress. The patella aka the kneecap actually protects and covers the anterior articular surface of knee joint. It is the largest sesamoid bone in the body. Babies do have a soft body so with respect to that they also have a soft patella made of cartilage.

So if we consider the kneecap as a piece of bone the babies don’t actually have that but when we are considering does baby have kneecaps as cartilage then they have it.

 Conclusion

There are many things in the world which cannot be described scientifically the baby kneecap is one of them. There is no proper explanation for the babies having cartilaginous kneecaps. But the most accepted assumption is that babies have more physical activities than the adults and cartilage is less prone to breakage than bones.
