Fetus Skeleton

Unlike adults, the skull of a baby after birth is not a fused piece, but is composed of multiple bones, with gaps between each bone and the ability to move within a certain range.
The brain of children continues to develop, and the skull also grows and changes accordingly. The development of the skull can be measured by standards such as the size of the head circumference, the timing of closure of the cranial sutures and fontanels.
Spinal development
Before the age of 1, the growth of the spine is faster than that of the limbs. The baby’s movement development is adapted to the development of the spine.
E. Long bone development
The growth and development of long bones are gradually completed from the fetusto adulthood. The height of a person mainly depends on the growth and development of long bones.
