The cerebral peduncles are the two stalks that attach the
The cerebral peduncles are located on either side of the midbrain and are the frontmost part of the midbrain, and act as the connectors between the rest of the
ImportantStructure
The descending upper fibers from the internal capsule continue on through the midbrain and are then seen as the fibers in the cerebral peduncles.[5] The corticopontine fibers are found in the outer and inner third of the cerebral peduncle, these are the cortical input to the pontine nuclei.[6] The corticobulbar and corticospinal fibers are found in the middle third of the cerebral peduncle.[7] The corticospinal tract exits the internal capsule and is seen in the mid portion of the cerebral peduncles.
Cranial nerves
Cranial nerve 3 (oculomotor nerve) appears ventrally between the two cerebral peduncles in the interpeduncular fossa. Cranial nerve 4 (trochlear nerve) wraps around the lowest part of the cerebral peduncle.[8]
