What are the three lobes found in the cerebellum?

Answer explanation

Cerebellar Lobes

- Anterior lobe

- Posterior lobe

- Flocculonodular lobe

The peduncles of the cerebellum connect it to the rest of the central nervous system. Match the correct cerebellar peduncle with the connection it has to the specific part of the CNS.

• Afferent fibres to the pons

• Middle cerebellar peduncle

• Cerebellar efferent fibres to the midbrain

• Superior cerebellar peduncle

• Afferent and efferent fibres to the medulla

• Inferior cerebellar peduncle
