The corpus striatum (striated body) is a compound structure consisting of thestriatum and theglobus pallidus .cite web |url=http://thalamus.wustl.edu/course/cerebell.html |title=Basal Ganglia and Cerebellum |format= |work= |accessdate=]Definitions
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 capsule collectively. 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 thelentiform nucleus (also known as thelenticular nucleus ) and thecaudate nucleus * According to BrainInfo it is a part of the basal ganglia comprising the
globus pallidus andstriatum .cite web |url=http://braininfo.rprc.washington.edu/Scripts/ancilcentraldirectory.aspx?ID=255 |title=BrainInfo |format= |work= |accessdate=]Appearance
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.
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 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
