The pons (Latin: bridge) and
medulla (Latin: marrow) are
parts of the brainstem.
The basal ganglia (bundles)
comprise the striatum (caudate
nucleus and putamen), the
globus pallidus, the substantia
nigra, the nucleus accumbens,
and the subthalamic nucleus.
"Striatum" comes from the
obsolete term corpus striatum
(Latin: striped body).
