  Frontal bone - Wikipedia, the free encyclopedia
Below the frontal eminences, and separated from them by a shallow groove, are two arched elevations, the superciliary arches; these are prominent medially, and are joined to one another by a smooth elevation named the glabella.
The superior surface is convex, and marked by depressions for the convolutions of the frontal lobes of the brain, and faint grooves for the meningeal branches of the ethmoidal vessels.
The frontal articulates with twelve bones: the sphenoid, the ethmoid, the two parietals, the two nasals, the two maxillæ, the two lacrimals, and the two zygomatics.

The squamosal suture arches backward from the pterion and connects the temporal squama with the lower border of the parietal: this suture is continuous behind with the short, nearly horizontal parietomastoid suture, which unites the mastoid process of the temporal with the region of the mastoid angle of the parietal.
In or near the occipitomastoid suture is the mastoid foramen for the passage of the mastoid emissary vein.
In the frontoethmoidal suture are the anterior and posterior ethmoidal foramina, the former transmitting the nasociliary nerve and anterior ethmoidal vessels, the latter the posterior ethmoidal nerve and vessels.

 Skull - Wikipedia, the free encyclopedia
The bones of the roof of the skull are initially separated by regions of dense connective tissue called "sutures".
There are five sutures: the frontal suture, sagittal suture, lambdoid suture, coronal suture, and squamosal suture.
Most sutures are named for the bones they articulate, but some have special names of their own.

Bianchi established the independent development of the superciliary ridges apart from the simultaneous development of the frontal sinuses: and it is common experience to note that the congenital absence of frontal sinuses is not necessarily accompanied by absence of the superciliary ridges.
For these determinations the anthropologist studies the state of fusion of the basilar suture, that of the epiphyses of the long bone, the stage of dentition, the condition of the teeth and alveolar processes, and the state of the sutures of the vault of the skull (Hrdlieka).
The progression of fusion of sutures is the same internally and externally, although frequently it is asymmetrical at the levels of the transversal and lateral sutures.

Schwalbe also determined the position of the bregma (distance of the base point of the bregma-verticals from the glabella) and the index of this position to the glabella-inion line, the glabella-cerebral index (ratio of the tendon of the glabella arch to the tendon of the arch of the frontal bone).
