Fontanels are soft spots on an infant's skull where the bones have not yet fused together.
These areas are crucial for allowing the skull to be flexible during childbirth and for accommodating rapid brain growth after birth.
Fontanels are located at the junctions of the cranial bones, specifically where the sutures intersect.
The major fontanels include the anterior fontanel, located at the top of the head, and the posterior fontanel, located at the back of the head.
As the infant grows, these fontanels gradually close as the cranial bones fuse, typically completing by the age of 2 years.
