MICROANATOMY

Detailed explanation-1: -The largest component of the basal ganglia is the corpus striatum which contains the caudate and lenticular nuclei (the putamen, globus pallidus externus, and internus), the subthalamic nucleus (STN), and the substantia nigra (SN). These structures intricately synapse onto one another to promote or antagonize movement.

Detailed explanation-2: -Where are the basal ganglia located? The basal ganglia aren’t a single structure in your brain. Instead, they include several structures, ganglia and nuclei alike, found at the center of your brain.

Detailed explanation-3: -The lentiform nucleus, or lenticular nucleus, comprises the putamen and the globus pallidus within the basal ganglia. With the caudate nucleus, it forms the dorsal striatum. It is a large, lens-shaped mass of gray matter just lateral to the internal capsule.
