cerebellar afferent fibers from cerebral cortex

Question 1

what are the cerebellar afferent fibers from cerebral cortex

Answer 1

cotricopontocerebellar pathway

cerebro-olivocerebellar pathway

cerebroreticulocerebellar pathway

Question 2

fucntion of cerebellar afferent fibers from cerebral cortex

Answer 2

control voluntary movement

monitor and adjust muscle activity

Question 3

discuss path of cotricopontocerebellar pathway

Answer 3

fibers arise from frontal, parietal, temporal and occipital lobes

tas mag descend corono radiata - internal capsule - cerebral peduncles

the synapse sa pontine nuc

will enter opposite cerebellar hemisphere as MCP

maging mossy fibers

Question 4

significance of synapse in pontine nuc (cotricopontocerebellar)

Answer 4

will form pontocerebllar fibers that decuss = transverse fibers of pons

Question 5

cotricopontocerebellar fibers gives rise to _____

Answer 5

mossy fibers

Question 6

discuss path of cerebro-olivocerebellar pathway

Answer 6

fibers arise from frontal, parietal, temporal and occipital lobes

tas mag descend corona radiata - internal capsule

then terminate on inferior olivary nuc of same side

mag deccusate and enter contralat ICP to enter cerebellar hemisphere

terminates as climbing fibers in cerebellar cortex

Question 7

discuss path of cerebroreticulocerebellar pathway

Answer 7

fibers arise from nerve cells of sensorimotor cortex

terminates in ipsi and contra reticular formation in pons and medulla

give rise to reticulocerebellar fibers tas enter ipsi cerebellar hemis via ICP and MCp
