Fontanels
The fontanels allow the fetal skull to be compressed slightly during birth and also allow for brain growth during late fetal life.

Well, first of all.Fontanelsare spot spots in the skull that allows the skull to expand as the brain increases in size & also helps the fetal skull flex and squeeze through the birth canal during delivery. Adults lack fontanels because by the time you are an adult, your brain is already fully developed and by the age of four, most of the bones in the skull have ossified across the their fontanels.
A fontanel is a soft spot on a baby's head where the skull bones have not yet fused together. There are typically several fontanels on a newborn's head to allow for the baby's brain growth and development. Over time, these fontanels will close as the skull bones fully develop.
Anterior (frontal) Fontanel Posterior (occipital) Fontanel Anterolateral (sphenoid) Fontanel Posterolateral (mastoid) Fontanel
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.
A fetal skull has six fontanels: two anterior (sagittal and frontal) and four posterior (two squamous and two mastoid). These membranous gaps eventually close as the skull bones fuse together during infancy.

The fontanels of a baby skull are made of connective tissue. They are soft spots between the skull bones that allow for some flexibility during birth and rapid brain growth in the first year of life. Over time, these fontanels close as the bones of the skull fuse together.
Fontanels are soft spots on a baby's skull where the bones have not yet fused together. The most notable fontanels are located on the top of the head (anterior fontanel) and at the back (posterior fontanel). There are also smaller fontanels located on the sides of the head (sphenoidal and mastoid fontanels). These areas allow for the skull to accommodate the growing brain and facilitate childbirth.
