The brow ridge is a nodule or crest of bone situated on the frontal bone of the skull. It forms the separation between the forehead portion itself (the squama frontalis) and the roof of the eye sockets (the pars orbitalis ). Normally, in humans, the ridges arch over each eye, offering mechanical protection.From this protuberance the upper division of the cruciform eminence runs to the superior angle of the bone, and on one side of it (generally the right) is a deep groove, the sagittal sulcus, which lodges the hinder part of the superior sagittal sinus. To the margins of this sulcus the falx cerebri is attached.This pdf guide provides detailed information on the Stablecut Saw Blades, a range of high-performance cutting instruments for large bone surgery.
