In the human brain, the superior cerebellar peduncle (brachium conjunctivum) is one of the three paired cerebellar peduncles of bundled fibers that connect the cerebellum to the brainstem. The superior cerebellar peduncle connects to the midbrain. It consists mainly of efferent fibers, the cerebellothalamic tract that runs from a cerebellar ...
The cerebellar peduncles are three paired bundles of fibres that connect the cerebellum to the brain stem. [1] Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain. Middle cerebellar peduncles connect the cerebellum to the pons and are composed entirely of centripetal fibers.
The cerebellum follows the general groups-of-three pattern found in anatomy, [17] with three major input and output cerebellar peduncles (fiber bundles). These are the superior (brachium conjunctivum), middle (brachium pontis), and inferior (restiform and juxtarestiform bodies) cerebellar peduncles.
It communicates with the cerebellum by the superior cerebellar peduncles, which enter at the caudal end, medially, on the ventral side; the cerebellar peduncles are distinctive at the level of the inferior colliculus, where they decussate, but they dissipate more rostrally. [9]
The cerebral peduncles (In Latin, ped-means 'foot'.) are the two stalks that attach the cerebrum to the brainstem. [1] They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) tracts that run to and from the cerebrum from the pons.
The superior cerebellar peduncle is mainly an output to the cerebral cortex, carrying efferent fibers via thalamic nuclei to upper motor neurons in the cerebral cortex. The fibers arise from the deep cerebellar nuclei. The middle cerebellar peduncle is connected to the pons and receives all of its input from the pons mainly from the pontine ...
The arteries of the base of the brain. Superior cerebellar artery labeled near center. The temporal pole of the cerebrum and a portion of the cerebellar hemisphere have been removed on the right side (left half of diagram). Inferior aspect (viewed from below). The superior cerebellar artery supplies deep parts and superior parts of the cerebellum.
The cerebellothalamic tract or the tractus cerebellothalamicus, is part of the superior cerebellar peduncle. It originates in the cerebellar nuclei, crosses completely in the decussation of the superior cerebellar peduncle, bypasses the red nucleus, and terminates in posterior division of ventral lateral nucleus of thalamus. The ventrolateral ...
