In the human body, the 'Basal ganglia' are a group of subcortical nuclei located deep within the cerebral hemispheres. They are primarily involved in: MCQ with Answer and Explanation

The basal ganglia are a group of interconnected subcortical nuclei (including the caudate nucleus, putamen, globus pallidus, substantia nigra, and subthalamic nucleus) located deep within the white matter of the cerebral hemispheres. They are crucial components of the extrapyramidal motor system. Their primary functions are to regulate voluntary motor movements (by facilitating desired movements and inhibiting unwanted ones), procedural learning (learning by repetition), routine behaviors, and habit formation. Dysfunction of the basal ganglia leads to movement disorders like Parkinson's disease and Huntington's disease.
