Alternative Content 5.3: Subcortical Systems Involved in Movement

The subcortical systems involved in movement are the caudate nucleus in front, the putamen behind the caudate nucleus, the globus pallidus behind the putamen, the subthalamic nucleus behind the globus pallidus, the substantia nigra behind the subthalamic nucleus, and the cerebellum behind the substantia nigra.

 

Review the subcortical systems involved with movement.

Globus pallidus

The basal ganglia include a group of interconnected forebrain nuclei: the caudate nucleus, putamen, and globus pallidus.

Caudate nucleus

The basal ganglia include a group of interconnected forebrain nuclei: the caudate nucleus, putamen, and globus pallidus.

Putamen

The basal ganglia include a group of interconnected forebrain nuclei: the caudate nucleus, putamen, and globus pallidus.

Subthalamic nucleus

The subthalamic nucleus in the ventral thalamus is closely associated with the motor functions of the basal ganglia. The subthalamic nucleus is part of a circuit that provides inhibitory influences on the basal ganglia, and reinforces the suppression of inappropriate movements.

Substantia nigra

The darkly-pigmented substantia nigra contains dopamine-containing cells that project to the basal ganglia. Degeneration of these cells can lead to Parkinson’s disease.
