subthalamus
- This part of the diencephalon is wedged laterally between the
thalamus and the hypothalamus.
- It is important for regulating movements produced by skeletal
muscles.
- It is, not surprisingly, interconnected with other structures
important in movement, such as the basal ganglia and substantia nigra.
- The bulk of the subthalamus is made up of the subthalamic
nucleus and another gray matter component is the zona incerta. There are also
several fiber bundles in the subthalamus. They are the: subthalamic fasciculus,
lenticular fasciculus, and ansa lenticularis.
