Parietal Bones Flashcards
Where is the frontal angle
This is at the point of bregma in the middle, normally 90 degrees
Where is the sphenoidal angle
Located at pterion more of a point
where is the occipital angle
Located at lambda
Where is the mastoid angle
This is located at asterion
Where is the temporal line
Found on the ectocranial surface
When present where is the parietal foramen
Located close to the sagittal suture
Where is the parietal striae
Lines up from the squamous margin
Where are the meningeal grooves
Dominate the endocranial surface - blood vessels
What is the sagittal sulcus
This is made when the parietals are articulated and the grooves combine along the midline
Where is the arachnoid foveae
These are found along the sagittal edge of each parietal endocranially
Where is the sigmoid sulcus or edge of the groove for the sigmoid sinus
This is found at the mastoid angle
Where is the sagittal margin
The side where the sagittal suture would be
Where is the frontal margin
Where the frontalparietal suture is
Where is the occipital margin
Where the lambdoid suture would be
Where is the squmous margin
This is where the parietal meets the temporal
