The corpus striatum (striated body) is a compound structure consisting of the
striatumand the globus pallidus.cite web |url=http://thalamus.wustl.edu/course/cerebell.html |title=Basal Ganglia and Cerebellum |format= |work= |accessdate=]
The term has been used in a few different ways:
* It is sometimes used as another term for the
basal ganglia. Fact|date=April 2008
* It may also refer to both the basal ganglia and
internal capsulecollectively. cite web |url=http://www.csuchico.edu/~pmccaffrey/syllabi/CMSD%20320/362unit2.html |title=General Description of the Central Nervous System |format= |work= |accessdate=]
* According to the 1917 version of
Gray's Anatomy, it is the combination of the lentiform nucleus(also known as the lenticular nucleus) and the caudate nucleus
* According to BrainInfo it is a part of the basal ganglia comprising the
globus pallidusand striatum.cite web |url=http://braininfo.rprc.washington.edu/Scripts/ancilcentraldirectory.aspx?ID=255 |title=BrainInfo |format= |work= |accessdate=]
From lateral to medial, the corpus striatum is composed of the external capsule (white matter), the lentiform nucleus (gray matter), the internal capsule (white matter), and the caudate nucleus (gray matter). The alternating white and gray matter give it a striated appearance.
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 ventricle; it is termed the extraventricular portion, or the
The remainder, however, projects into the ventricle, and is named the intraventricular portion, or the
