| 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
