basal ganglion

An individual member of a collection of basal ganglia. Basal ganglia are subcortical masses of gray matter in the forebrain and midbrain that are richly interconnected and so viewed as a functional system. The nuclei usually included are the caudate nucleus (caudoputamen in rodents), putamen, globus pallidus, substantia nigra (pars compacta and pars reticulata) and the subthalamic nucleus. Some also include the nucleus accumbens and ventral pallidum[NIF,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the basal ganglion is

An individual member of a collection of basal ganglia. Basal ganglia are subcortical masses of gray matter in the forebrain and midbrain that are richly interconnected and so viewed as a functional system. The nuclei usually included are the caudate nucleus (caudoputamen in rodents), putamen, globus pallidus, substantia nigra (pars compacta and pars reticulata) and the subthalamic nucleus. Some also include the nucleus accumbens and ventral pallidum[NIF,modified]. The atlas records it as a nerve at the organ scale in the human body.

Where the basal ganglion is

It sits within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the basal ganglion connects to

The atlas records 11 typed relationships for it, across 4 kinds of connection. part of brain and collection of basal ganglia.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the basal ganglion. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as basal ganglion of telencephalon, basal ganglia, basal nucleus and nuclei basales. Searching any of those names reaches this page.

Questions

Where is the basal ganglion?

It sits within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the basal ganglion connect to?

Part of: brain and collection of basal ganglia.

Is the basal ganglion the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
