Morphology
The phrase is compositionally transparent: 'subthalamic' means 'pertaining to the region under the thalamus' and 'nucleus' denotes a cluster of neuronal cell bodies, so the overall meaning — a nucleus located in the subthalamus — follows directly from the constituents. This follows standard adjective+noun medical naming conventions (common across languages), so a learner who knows both parts can predict the MWE's meaning.
Etymology
Subthalamic nucleus is made of three parts: sub meaning 'under', thalamic from the thalamus meaning a central brain area, and nucleus meaning a 'small center'. Picture a small button under a larger main area that helps control movement, so the subthalamic nucleus is a tiny part under the thalamus that helps 'control movement'.
