Human Anatomy Brain and Cranial Nerves
Examples of Dural Venous Sinuses
1)Superior Sagittal Sinus 2)Transverse Sinus 3)Sigmoid Sinus
Definition/Function-Dural Venous Sinuses
Channels that allow venous return from brain to heart
Cranial Meninge-Serves to form Dural Venous Sinuses
Dura Mater
Meningeal Layer of the Dura occasionally separates itself from the periostal layer forming_____________ _____________.
Dural Infolding
When External Pariostal Layer and Internal Meningeal Layer of Dura Mater separate at certain parts of the brain, __________ __________ __________are formed allowing venous blood flow from the brain.
Dural Venous Sinuses
Dural Venous Sinuses are lined by ____________.
Endothelium
2 fibrous connective tissue layers that make up Dura Mater
External Pariostal Layer and Internal Meningeal Layer
Fold that divides the Cerebellar Hemispheres
Falx Cerebelli
Fold that anchors to Crista Galli
Falx Cerebri
Fold that dips into the longitudinal fissure and divides cerebral hemispheres
Falx Cerebri
Through which foramen does the Middle Meningeal Artery pass?
Foramen Spinosum
Where does blood all blood from DVS's eventually flow to?
Internal Jugular Vein
Artery-blood supply to the dura mater
Middle Meningeal Artery
Dura Mater- decription
Most Superficial, tough, external fibrous layer, adheres to the inside of cranium
Sinus that directs blood into Internal Jugular Vein at Jugular foramen
Sigmoid Sinus
3 Cranial Meninges
Superficial to Deep 1)Dura Mater 2)Arachnoid Mater 3)Pia Mater
Sinus that forms superior margin of Falx Cerebri
Superior Sagittal Sinus
Fold that connects to falx cerebri hint: tent over the cerebellum
Tentorium Cerebelli
Infolding that extends into the transverse fissure between cerebrum (occipital lobes) and cerebellum.
Tentorium Cerebelli
SCALP is an acronym referring to.....
The 5 layers of the Scalp (Superficial to Deep) 1) S-kin 2) C-onnective Tissue 3) A-Epicranial Aponeurosis 4) L-oose Connective Tissue 5) P-ericranium
Sinus that forms outer margin of Tentorium Cerebelli
Transverse Sinus
Dura Mater adheres to....
the inside of the cranium
