The pons extends from the pontomedullary junction to an imaginary line drawn from the exit of cranial nerve IV. Dorsal to the pons lies the cerebellum. The cerebellum receives information and projects information back to the brainstem through the inferior, middle, and superior cerebellar peduncles. Important structures at this level include corticospinal tracts, corticopontocerebellar fibers travelling through the middle cerebellar peduncle, the cerebellum, and cranial nerves V through VIII.
