Brain And Environs: One Liners

Front 1

SCALP

Back 1

Skin - Connective Tissue - Aponeurotica - Loose Areolar CT - Pericranium (periosteum)

Front 2

Anterior Fossa

Back 2

Contains Frontal Lobe, divided from the middle fossa by the lesser wing of sphenoid bone

Front 3

Middle Fossa

Back 3

Contains Temporal lobe, divided from the posterior fossa by the petrous ridge of the temporal bone as well as by a sheet of meninges - Tentorium Cerebelli

Front 4

Posterior Fossa

Back 4

Contains the cerebellum and brainstem

Front 5

Falx Cerebri

Back 5

Flat sheet of Dura that is suspended from the roof of the cranium and separates the right and left cerebral hemispheres, running in the interhemispheric fissure

Front 6

Tentorium Cerebelli

Back 6

Tent like sheet of Dura that covers the upper surface of the cerebellum

Front 7

Supratentorial

Back 7

Above the Tentorium Cerebelli

Front 8

Infratentorial

Back 8

Below the Tentorium Cerebelli

Front 9

Tentorial Notch

Back 9

Also known as Tentorial Incisure, narrow opening in the tentorium cerebelli which the midbrain passes through. At the level of CNIII and the Interpeduncular fossa.

Front 10

Virchow-Robin Space

Back 10

where pia surrounds initial portion of each blood vessel as it penetrates the brain surface forming a perivascular space and then fuses with the blood vessel wall

Front 11

Epidural Space

Back 11

between dura and skull; contains the middle meningeal artery

Front 12

Middle Meningeal Artery

Back 12

Enters skull through the foramen spinosum and runs in the epidural space between the Dura and the skull

Front 13

Subdural Space

Back 13

Potential space between the inner layer of Dura and the loosely adherent arachnoid

Front 14

Bridging Veins

Back 14

Traverse the subdural space and drain the cerebral hemispheres and pass through the subdural space en route to several large Dural venous sinuses

Front 15

Dural Sinuses

Back 15

Large venous channels that lie enclosed within the two layers of Dura, Dural sinuses drain blood mainly via the sigmoid sinuses to reach the internal jugular vein.

Front 16

Subarachnoid Space

Back 16

CSF filled space between arachnoid and pia, also major arteries of the brain travel within the subarachnoid space and then send smaller penetrating branches inward through the pia

Front 17

Epidural Fat

Back 17

In spinal canal only layer between the Dura and the periosteum

Front 18

Ependymal cells

Back 18

line the ventricles

Front 19

Choroid Epithelial Cells

Back 19

Blood vessels of the choroid plexus are lined with ependymal like cuboidal cells called Choroid Epithelial Cells

Front 20

Lateral ventricles

Back 20

"one in each cerebral hemisphere
