Coronal suture
Placed between the frontal bone and two parietal bones

Placed in the median plane between two parietal bones
Lambdoid suture
Lies posteriorly between the occipital and parietal bones
Bregma
The meeting point between the coronal and sagittal sutures
Lambda
The meeting point between the sagittal and lambdoid sutures
Anterior fontanelle
A membranous gap junction of the coronal and sagittal sutures that closes at 1 to 1 and a half years
Posterior frontanelle
A membranous gap in the junction of the sagittal and lambdoid sutures that closes at 2 to 3 months of age
