How Many Bones Do Babies Have Compared to Adults

Why do babies have more bones than grownups?

Babies have more bones than grownups because as they mature, a few of the bones fuse together to form one bone. This is because babies have more cartilage than bone. New born babies have around 305 bones. A baby’s skeleton is mainly comprised of cartilage. As a person grows up, the majority of this cartilage becomes bone in a procedure called ossification. By adulthood, the skeleton has simply 206 bones.

Cartilage is a rubber-like cushioning that covers and shields the ends of long bones at the joints. It is generally a smooth, flexible tissue that can be readily found in the ears, rib cage, nose and other parts of the body. Cartilage is neither as strong as bone nor as flexible as muscle.

Q: How many bones does a newborn human baby have versus a grownup?

A: A human baby is born with 176 true bones, however its skull is actually three bones that have actually not yet fused. (This is a great feature considering that it enables simpler delivery when the baby is born.) As a baby grows, the three bones fuse into one. Some of a baby’s other bones are called cartilaginous bones, which means they have actually not yet calcified. By the time a baby reaches adulthood, bones will total 206 in his/her body.
