The basal ganglia is an important part of the brain which program impulses from cerebral cortex and initiates motor activities through cerebellum and corticospinal tracts. Parkinsonism is a disorder in which there is decrease in the dopaminergic neurons in the striatum which results in motor impairment.

The components of the basal ganglia are:

Corpus Striatum– Caudate+Lentiform nucleus.

Lentiform nucleus– Putamen+Globus pallidus.

Striatum – Caudate nucleus+Putamen.
