MICROANATOMY

Detailed explanation-1: -The globus pallidus and putamen collectively form the lentiform (lenticular) nucleus, which lies beneath the insula. The caudate nucleus and putamen form the corpus striatum. The corpus striatum is also an important part of the basal ganglia.

Detailed explanation-2: -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-3: -As a part of the basal ganglia, the lentiform nucleus (LN) is a lens-shaped, bilateral structure in the basal ganglia bounded by the internal and external capsules and has three components: the internal and external globus pallidus and the putamen (Hibar et al., 2013).

Detailed explanation-4: -The globus pallidus is a triangular-shaped, subcortical structure of the brain. It is located below the cerebral cortex, medial to the putamen. The globus pallidus is part of a large group of subcortical nuclei called basal ganglia.
