Obelion is a nearly constant existing anthropological landmark. It is defined as the midpoint between both Foramina parietalia (for typical venous Emissaria connecting veins of galea with Sinus sagittalis sup.). Obelion is located on Suturus sagittalis.
The sagittal border usually runs directly posteriorly from the rounded frontal angle for about two-thirds of its length. This is the position of the obelion, and there may be a parietal notch in the bone (Fig. 4.37) after which the serrations on the border become more fringe-like as it slopes away towards the rounded occipital angle at the posterior fontanelle.
Use obelion when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
