ABSTRACT
This chapter provides that the themed presentation encourages quick, focused study and detailed answers aid comprehension and encourages familiarity with pathophysiology with essential diagrams, colour images and sample MRIs. During neural development, the lumen of the neural tube is lined with neural stem cells that in adults differentiate into ependymal cells lining the ventricular system. These cells are ciliated cuboidal epithelial cells, and modified ependymal cells in the lateral, third and fourth ventricles form the choroid plexus, which is responsible for the production of CSF. Poliovirus, which is transmitted by the faecal-oral route, causes poliomyelitis. It is most often seen in developing countries in young unimmunised children. The virus replicates in the oropharynx and small intestine before spreading through the bloodstream to the CNS. Selegiline selectively inhibits monoamine oxidase B therefore increasing the availability of the dopamine in Parkinson’s disease.
