Groove for superior sagittal sinus

The groove for superior sagittal sinus is a shallow depression that runs along the middle of the inside surface of the calvaria, the upper part of the skull. It originates as a narrow groove from the frontal crest and gradually widens as it progresses towards the posterior region of the skull. This groove creates a cavity for the superior sagittal sinus and its edges act as attachment sites for the falx cerebri. Moving towards the rear of the skull, the groove extends and merges with the groove for the transverse sinus on the right side of the occipital bone, close to the internal occipital protuberance.
