largest part of the superolateral surface of cerebral cortex?
Middle cerebral artery
Which direct branch of the internal carotid artery supplies the
largest part of medial surface of cerebral cortex?

Name three areas of the brain which are devoid of blood-brain
barrier?
Area Postrema
Median Eminence (Hypothalamus)
Pineal gland
What are the names of (both potential and real) spaces between
the layers of the cranial meninges?
Epidural space(real), subdural space(potential), subarachnoid
space(real)
Which diencephalic structures are parts of the Papez circuit?
Mammillary body; Anterior thalamic nuclei

What are the choroid plexuses? What are their function?
a plexus of cells that arises from the tela choroidea in each of the ventricles of the brain.
Invagination of the vascular pia mater into the ventricles that produce CSF.
What are the layers of the meninges?
Dura mater, Arachnoid mater, pia mater
Where does the absorption of CSF take place? Which
anatomical structures are involved in this process?
From the subarachnoidal space into the superior sagittal sinuses.
Arachnoid granulations (Pacchionian granulations) are involved.
What is the interpretation of the allocortex?
The allocortex is a region of the cerebral cortex that has three layers
What is the interpretation of the isocortex?
Also called neocortex. It is characterized by having 6 cell layers.

dopaminergic neurons?
Substantia nigra
What is the function of the area postrema?
Chemical vomiting centre
