|
Falx Cerebri |
- Dural fold between the two cerebral hemispheres - superior fixed margin, inferior free margin - Anchored to: --> Internal occipital protuberance- posterior region --> crista galli- anterior region |
|
|
Fall Cerebelli |
- Dural fold between the two cerebellar hemispheres - Posterior fixed margin, anterior free margin - anchored to: --> occipital bone |
|
|
Tentorium Cerebelli |
- Forms a roof or tent over the cerebellum - separates the cerebellum from the cerebrum -Anchored to: --> fall cerebri -->occipital bone -->petrous part of the temporal bone -->anterior and posterior clinoid processes |
|
|
Diaphragma Sellae |
- Forms a roof of the hypophyseal fossa - central opening for the infundibulum of the pituitary gland (opening for the stalk of the pituitary gland to pass through) - Anchored to: --> anterior and posterior crinoid processes |
|
|
Superior sagittal sinus |
- travels along the midline in the superior margin of falx cerebri -drains into: confluence of sinuses - forms the right transverse sinus |
|
|
inferior sagittal sinus |
- tranverls along the inferior border of the falx cerebri - drains into: straight sinus |
|
|
straight sinus |
- travels posteriorly at junction of falx and tentorium cerebelli - Drains into: confluence of sinuses - forms the left transverse sinus |
|
|
Occipital sinus |
- travels in the fixed margin of the falx cerebelli against the occipital bone - Drains into: confluence of sinuses |
|
|
Confluence of sinuses |
- dilated space at the interval occipital protuberance - superior sagittal sinus, occipital sinus, and straight sinus drain into here - Drained via: right and left traverse sinus |
|
|
Transverse sinus |
- travel within the fixed margin of the tentorium cerebelli - right transverse sinus receives blood from the superior sagittal sinus - Left transverse sinus receives blood from the straight sinus - Drain into: sigmoid sinuses |
