Cerebral Hemispheres Flashcards
What forms the outer mantle and inner core of the cerebral hemispheres?
Outer mantle: gray matter; inner core: white matter
How is the surface area of each cerebral hemisphere maximized?
Through convolutions (~1 m² per hemisphere)
What structure separates the cerebral hemispheres?
Longitudinal fissure
What fibers connect the two hemispheres?
Commissural fibers (corpus callosum)
Name the components of the diencephalon.
Epithalamus, thalamus, subthalamus, hypothalamus
What are the primary functions of the ventricular system?
CSF production, transport, and removal; brain cushioning; buoyancy
What type of cells line the ventricles and produce CSF?
Ependymal cells
Where are the lateral ventricles located?
In the hemispheres, projecting into the frontal, occipital, and temporal lobes
Which ventricle connects to the lateral ventricles via the foramen of Monro?
Third ventricle
Where does the fourth ventricle drain CSF?
Into the spinal canal and subarachnoid cisterns
Name the three components of the brainstem.
Medulla oblongata, pons, midbrain
What vital functions does the brainstem control?
Respiration, cardiovascular regulation, consciousness
Where is the cerebellum located?
Below the pons
What are the three lobes of the cerebellum?
Flocculonodular, anterior, posterior
Which cerebellar lobe is responsible for balance and spatial awareness?
Flocculonodular lobe
