The largest part of the brain is also divided into...
- The cerebrum
- Cerebral hemispheres
Below the cerebrum and separate from it is the...
Both the cerebrum and the cerebellum grow out of the _________ which continues below with the ______ ______
Each cranial fossa is occupied by which part of the brain?
- Anterior CF = Frontal Lobe
- Middle CF = Temporal lobes
- Posterior CF = Cerebellum + Brainstem
The cranial cavity is lined throughout by this tough shiny fibrous tissue:
Dura, passes below through the foramen magnum becoming the Dura that lines the vertebral canal
This extension of dura separates the posterior cranial fossa from the rest of the cranial cavity and the cerebellum below with the Cerebrum above.
The opening in the Tentorium in which the brainstem passes through is called
Tissue that forms a midline partition between the two cerebral hemispheres and attaches to the Tentorium posteriorly and anteriorly to the ______ _____
The triangle that forms at the attachment of the Falx cerebri above is called the
Superior sagital sinus
The meninges are formed by:
The glossy surface on the outer brain that extends into each Sulcus and back out into each Gyrus is called
- The Pia.
- Each vessel that goes into the brain carries a sleeve of Pia along with it
This delicate transparent membrane, that does NOT extend into the Sulcii, it just bridges over from one Gyrus to the next.
Outside of the arachnoids (with no attachment to it) is this tougher layer of tissue that forms the meninges. Can be separated from the overlying bone.
These arteries run in the thickness of the Dura
The middle meningeal artery
