Study Notes
Structural Organization of the Brain and Ventricular System
- The cerebellum consists of bilaterally paired cerebellar hemispheres separated from the cerebral hemispheres by the transverse fissure.
- The cerebral cortex is a layer of grey matter, 4-6 mm thick, highly folded in sulci and gyri, which increases surface area.
- The brain is divided into anatomical regions called lobes, including the frontal, parietal, temporal, and occipital lobes.
- The brain is covered by several layers, including the skin, periosteum, cranium, dura mater, and meninges.
- The dura mater forms rigid folds in major fissures, such as the falx cerebri and tentorium cerebelli, separating different brain regions.
- The dural reflections in sagittal and coronal MRI images show the relationship with the brain lobes, cerebellum, and sinuses.
- The dural venous sinuses, including the superior sagittal sinus and transverse sinus, drain venous blood from the brain into internal jugular veins.
- The ventricular system originates from a hollow, fluid-filled tube, the neural tube, and contains cerebrospinal fluid (CSF) produced by the choroid plexus.
- The choroid plexus forms the blood-CSF barrier, and tight junctions between endothelial cells of cerebral blood vessels form the blood-ISF barrier.
- Breakdown of the blood-brain barrier (BBB) causes increased permeability of brain capillaries, leading to vasogenic edema and increased intracranial pressure.
- The ventricular system is associated with subdivisions of the nervous system, including the cerebral hemispheres, diencephalon, midbrain, pons, medulla, cerebellum, and spinal cord.
- The circulation of CSF involves its production by the choroid plexus, circulation through ventricles, and entry into the subarachnoid space via median and lateral apertures of the fourth ventricle.
