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 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.
Yes, both fetal and adult skulls have the same bones. However, the fetal skull is made up of separate bones that fuse together as the individual grows and develops. The adult skull is composed of 22 bones, including the mandible, maxilla, frontal bone, parietal bones, temporal bones, occipital bone, sphenoid bone, and ethmoid bone.
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.
Fetal skull moulding is the process by which a newborn's skull bones shift and overlap during passage through the birth canal, allowing for easier delivery. This molding is a normal part of the birthing process and typically resolves within a few days after birth as the skull bones return to their normal position.
