ABSTRACT

Introduction The blood vessels to an organ provide it with a relatively constant supply of oxygen and other nutrients and a means for removal of metabolic waste. Failure to meet these vital requirements results in disease in that organ. Because of the unique structure and organization of the nervous sys­ tem, localized abnormalities in its blood supply may pro­ duce devastating alterations in neural function. In this chapter, the normal anatomy and physiology o f the vas­ cular supply to neural tissue and the clinical manifestations of pathologic processes affecting this system are described.
