Anatomical terms of bone [edit on Wikidata]

The groove for transverse sinus is a groove which runs along the internal surface of the occipital bone, running laterally between the superior and inferior fossae of the cruciform eminence. The transverse sinuses travel along this groove.

A small or absent bony groove in the occiput in conjunction with the compressible nature of the transverse sinus makes this structure vulnerable to tapering with increased ICP. ^[1]
