The greater, or anterior fontanel, is a lozenge-shaped space that is situated at the junction of the sagittal and the coronal sutures. The lesser, or posterior fontanel, is represented by a small triangular area at the intersection of the sagittal and lambdoid sutures. The localization of these fontanels gives important information concerning ...

Anterior fontanelle is a diamond-shaped membrane-filled space located between the two frontal and two parietal bones of the developing fetal skull. It persists until approximately 18 months after birth. It is at the junction of the coronal suture and sagittal suture. The fetal anterior fontanelle may be palpated until 18 months.
It forms the main component of the skull roof. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. [1] In the human skull, the sutures between the bones normally remain flexible during the first few years of postnatal development, and fontanelles are palpable.
The frontal border is deeply serrated, and bevelled at the expense of the outer surface above and of the inner below; it articulates with the frontal bone, forming half of the coronal suture. The point where the coronal suture intersects with the sagittal suture forms a T-shape and is called the bregma.
Cranial height is defined as the distance between the bregma and the midpoint of the foramen magnum (the basion). [6] This is strongly linked to more general growth. [6] This can be used to assess the general health of a deceased person as part of an archaeological excavation, giving information on the health of a population.
The point where the upper temporal line cuts the coronal suture is named the stephanion. The stephanion is found anterior to the euryon (the most lateral point of the skull), and hence, the supramarginal gyrus. The stephanion is located on the same coronal plane as Broca's area (Brodmann's area 44–45). [1]
