Fontanels
The fibrous connections between the bones of a fetal skull are known as fontanelles. These are soft spots that allow for flexibility during birth and rapid brain growth in infancy. They eventually close and solidify as the bones of the skull fuse together.
The fibrous connections between the bones of a fetal skull are called sutures. These flexible joints allow for the skull to expand as the brain grows and also facilitate passage through the birth canal during delivery. In infants, these sutures are separated by fontanelles, or soft spots, which further contribute to the skull's adaptability during development. Over time, the sutures fuse as the child matures.
the fetal bones are much more delicate than the adult
Yes.
Yes, during fetal development, the skeleton initially forms as cartilage and fibrous structures that are later replaced by bone tissue in a process called ossification. The bones continue to grow and develop throughout childhood and into adolescence.

because fetal bones fuse together
no!
A fetal chick grows into a chicken, whereas a fetal human grows into a human.
The fetal skeleton is much softer, it has far more bones which fuse by adulthood. also the proporions are much more different, the skull of a fetus is much big in comparison to its body. obviously the fetal skeleton is much much smaller and is more fraile.as development of the facial area of a human develop, the head becomes much less round (so a fetal skeleton would have a rounder head). the face also becomes more defined and features more noticable. I hope this helps.
One of the membranous intervals between the uncompleted angles of the parietal and neighboring bones of a fetal or young skull; so called because it exhibits a rhythmical pulsation.
fontanellesthe membrane filled areas situated in between the bones present in the vault of the neonatal skull are called fontanelles.there are six fontanelles present at the time of birth. the two frontal bones are separated by the metopic suture.six fontanelles are :anterior fontanelle.posterior fontanelle.a pair of anterolateral fontanelles.a pair of posteriolateral fontanelles.the fontanelles help moulding of the foetal head during child birth.
