Emboliform
Fastigial
Name the lobes of the cerebellum.
Anterior lobe
Posterior lobe
Flocculonodular lobe
Name some functions of the cerebellum.
Coordination of voluntary movements such as posture, balance and coordination.
Which artery gives rise to the vertebral artery?
Subclavian artery
Which direct branch of the internal carotid artery supplies the 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?
Anterior cerebral artery
Name three areas of the brain which are devoid of blood-brain barrier.
Pituitary gland
Area postrema
Pineal
Which diencephalic structures are parts of the Papez circuit?
Mammillary body
Anterior thalamic nuclei
What are the names of (both potential and real) spaces between the layers of the cranial meninges?
Epidural space
Subdural space
Subarachnoid space
What are the functions of the limbic system?
Emotions, behaviour, memory, sexual stimulation
What brain areas are connected by the fornix?
Hippocampal formation to the mammillary bodies of the hypothalamus
What are choroid plexuses? What are their function?
The choroid plexus is a complex network of capillaries lined by specialized cells and has various functions. One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells.
What are the layers of the meninges?
Pia matter (innermost)
Arachnoid matter
Dura matter
Where does the absorption of CSF take place? Which anatomical structuresare involved in this process?
From subarachnoid space into the superior sagittal sinuses.
Arachnoid granulations are involved.
What is the interpretation of the allocortex?
The allocortex is one of the two types of cerebral cortex, it has 3-5 cell layers.
Types: archiocortex, paleocortex
What is the interpretation of the isocortex?
Also called neocortex, has 6 cell layers.
Which artery passes through the cavernosus sinus?
Internal carotid artery
What brain areas does basilar artery supply?
Pons, cerebellum, occipital lobe
Name three association fiber systems of the telencephalon.
Which mesencephalic area contains the highest density of dopaminergic neurons?
Substantia nigra
What is the function of the area postrema?
Chemical vomiting center
Which anatomical/physiological system includes the Papez circuit?
Limbic system
Name three commissural fiber systems of the telencephalon.
Corpus callosum
Anterior commissure
Hippocampal comissure
