Parietal Bone
| Question | Answer |
|---|---|
| Parietal eminence | sort of obvious where this is – it is the more circular part of the parietal bone that feels like an eminence, sort of in the middle going horizontally across the bone, closer to the bottom going vertically |
| Superior temporal line and inferior temporal line | continued from frontal bone |
| Parietal foramen | not always present, located close to the sagittal suture near lambda – sort of towards the posterior of the sagittal suture |
| Parietal striae | these are “rays” or striations that are located near the beveled edge of the parietal bone |
| Meningeal grooves | same as before, located on endocranial surface |
| Sulcus for the sigmoid (transverse sinus) | located on posterior suture (sigmoid? Suture) in the corner that connects with the beveled edge – only a very small portion of it is visible on the parietal bone |
| Channel (sulcus) for the superior sagittal sinus | continues from frontal – runs along the midline suture between the two parietals –difficult to see as it is cut off |
| Arachnoid foveae (granular foveae) | run along sagittal sulucs |
