Frontal crest

The frontal crest is a bony ridge found on the inside surface of the frontal bone's squamous part. It forms at the point where the two sides of the sagittal sulcus come together in the middle, creating the ridge known as the frontal crest. The falx cerebri, which is a structure made up of two dural folds, attaches along both sides of the sagittal sulcus. These folds stretch forward and attach to the frontal crest as well. Therefore, the frontal crest plays a crucial role as a forward anchoring point for the falx cerebri.
