The '''dorsal striatum''', '''corpus striatum''' or '''striated body''' is a compound structure in the brain, consisting of the [[caudate nucleus]], and the [[lentiform nucleus]] (which consists of the [[putamen]] and the [[globus pallidus]]).<ref name="urlBasal Ganglia and Cerebellum">{{cite web |url=http://thalamus.wustl.edu/course/cerebell.html |title=Basal Ganglia and Cerebellum |format= |work= |accessdate=}}</ref> It is a pair of nuclear masses that form the [[basal ganglia]], along with the [[subthalamic nucleus]] and the [[substantia nigra]]. |
|||
==Definition== |
|||
The term has been defined in a few different ways: |
|||
* According to the 1917 version of [[Gray's Anatomy]], it is the combination of the [[lentiform nucleus]] and the [[caudate nucleus]] |
|||
* According to BrainInfo it is a part of the basal ganglia comprising the [[globus pallidus]] and [[striatum]].<ref name="urlBrainInfo">{{cite web |url=http://braininfo.rprc.washington.edu/Scripts/ancilcentraldirectory.aspx?ID=255 |title=BrainInfo |format= |work= |accessdate=}}</ref> |
|||
* It may also refer to both the [[basal ganglia]] and the [[internal capsule]] collectively.<ref name="urlGeneral Description of the Central Nervous System">{{cite web |url=http://www.csuchico.edu/~pmccaffrey/syllabi/CMSD%20320/362unit2.html |title=General Description of the Central Nervous System |format= |work= |accessdate=}}</ref> |
|||
* It may also refer to the putamen and caudate collectively |
|||
==Anatomy== |
|||
A part of the dorsal 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 [[lentiform nucleus]]. |
|||
The remainder, however, projects into the ventricle, and is named the '''intraventricular portion''', or the [[caudate nucleus]]. |
|||
The dorsal striatum has received its name from the striped appearance presented by a section of its anterior part, in consequence of diverging white fibers mixed with the gray substance that forms its chief mass. From lateral to medial, there lies the [[external capsule]] (white matter), the lentiform nucleus (gray matter), the [[internal capsule]] (white matter), and the caudate nucleus (gray matter). |
