The alternating white and gray matter give it a striated appearance. ==Anatomy== The corpus striatum has received its name from the striped appearance which a section of its anterior part presents, in consequence of diverging white fibers being mixed with the gray substance which forms its chief mass. A part of the corpus striatum is imbedded in the white substance of the hemisphere, and is therefore external to the [[ventricular system|ventricle]]; it is termed the '''extraventricular portion''', or the [[lenticular nucleus]]. The remainder, however, projects into the ventricle, and is named the '''intraventricular portion''', or the [[caudate nucleus]]. ==References== {{reflist}} ==External links== * [http://www.umanitoba.ca/faculties/medicine/anatomy/csjb.htm University of Manitoba] * [http://www.ndif.org/Terms/corpus_striatum.html Definition of NDIF] * [http://merck.micromedex.com/index.asp?page=bhgfigures&article_id=BHG01NE11&figure=BHG01NE11F01 Image at Merck] {{Gray's}} ==See also== * [[striatum]] {{Basal ganglia}} [[Category:Cerebrum]] [[ru:Полосатое тело]]
