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
