The anterior fontanelle was soft at birth as this allows the baby's head to exit the birth canal safely. As the baby gets older, the fontanelle closes and hardens to a normal skull.
two "spots" generally combine to make up the larger spot. they are the posterior fontanel and the anterior fontanel
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.
Its called a fontanel
The four fontanels of an infant are the anterior fontanel, posterior fontanel, sphenoid fontanel, and mastoid fontanel. The anterior fontanel, located at the top of the head, is the largest and typically closes by 18-24 months. The posterior fontanel, situated at the back of the head, generally closes by 2-3 months. The sphenoid and mastoid fontanels are smaller and close within the first year of life.
"Fontanelle" (sometimes spelled "fontanel".) There are actually four of them, but the anterior fontanelle (directly on top) is usually the most noticeable.
Anterior (frontal) Fontanel Posterior (occipital) Fontanel Anterolateral (sphenoid) Fontanel Posterolateral (mastoid) Fontanel
The posterior fontanel would be in the back of the head. The coronal fontanel would be located in another part of the brain.
They gradually fuse, so that eventually there is no anterior fontanel (or posterior fontanel) either.
The anterior fontanel is the most dorsal fontanel, located at the intersection of the sagittal suture and the coronal suture on the top of the skull.
Babies are born with six fontanels, or soft spots, on their skull. These fontanels allow for flexibility during birth and rapid brain growth in infancy. Over time, they gradually close as the baby's skull bones develop and fuse together.
The anterior fontanel
The anterior fontanel is located at the top of a baby's head, towards the front. It is a soft spot where the skull bones have not yet fused together, allowing for some movement during childbirth and rapid brain growth in the first year of life.
