Morphology

cerebral + peduncle

Both constituents directly contribute to the meaning: 'cerebral' specifies the cerebrum/brain and 'peduncle' denotes a connecting nerve bundle. As an anatomical noun–noun compound, the phrase denotes the peduncle associated with the cerebrum, so a learner who knows both words can compose the overall meaning.

Etymology

Cerebral peduncle gives the image of two thick 'stalks' under the thinking part of the brain. The word cerebral means 'of the brain' and peduncle means a 'little stalk' or 'foot', so imagining these stalks carrying nerve signals between the top brain and lower parts helps explain why the term names the bundles that connect and send signals.
