cerebellar peduncle การใช้

• Inferior cerebellar peduncle integrates proprioceptive info and outputs to the vestibulocerebellum.
• Most of it appears as a broad anterior bulge cerebellar peduncles.
• The inferior cerebellar peduncle is the largest center through which balance info passes.
• The damage to the cerebellum or the inferior cerebellar peduncle can cause ataxia.
• The ventral spinocerebellar tract then enters the cerebellum via the superior cerebellar peduncle.
• Connecting the cerebellum to different parts of the nervous system are three paired cerebellar peduncles.
• The fibers of the ventral spinocerebellar tract then eventually enter the cerebellum via the superior cerebellar peduncle.
• These axons ascend to the pons where they join the superior cerebellar peduncle to enter the cerebellum.
• The whole of the cerebellum receives modulatory input from the inferior olivary nucleus via the inferior cerebellar peduncle.
• The inferior cerebellar peduncle receives input from afferent fibers from the vestibular nuclei, spinal cord and the tegmentum.
• The secondary neuronal axons continue to ascend ipsilaterally and then pass into the cerebellum via the inferior cerebellar peduncle.
• Then the fibers decussate and form the middle cerebellar peduncle, terminating in the cerebellar cortex as mossy fibers.
• The pontine axons projects via the contralateral middle cerebellar peduncle, terminating in the cerebellar cortex as mossy fibers.
• The fossa is bounded on either side by the inferior cerebellar peduncle, which connects the medulla to the cerebellum.
• Moving rostrally, the inferior, middle, and superior cerebellar peduncles are found connecting the midbrain to the cerebellum.
• Directly rostral to the superior cerebellar peduncle, there is the superior medullary velum and then the two trochlear nerves.
• The axons of the third-order neurons cross the midline and enter the cerebellum through the inferior cerebellar peduncle.
• The SCA supplies blood to most of the cerebellar cortex, the cerebellar nuclei, and the superior cerebellar peduncles.
• Their axons leave medially through the hilum, cross the midline, and ascend into the cerebellum via the inferior cerebellar peduncle.
• Most of these fibers cross over to the contralateral lateral funiculus via the anterior white commissure and through the superior cerebellar peduncle.
