Answer 23

-vestibylocerebellar output to vestibulospinal tracts
- spinocerebellar output to vestibulospinal, medial reticulospinal , and medial corticospinal tracts
- cerebrospinal output to lateral corticospinal and rubrospinal tracts
- cerebral cortex to cerebrocerebellum

Question 24

describe the corticopontocerebellar pathway

Answer 24

connects cerebrum with the cerebellum passing thru the pons and the contralateral middle cerebellar peduncle

Question 25

describe the cunocerebellar tract

Answer 25

receives information from the arms using muscle spindles and GTOs , uses the inferior peduncle

Question 26

describe the hypothalamus to the cerebellum connection

Answer 26

thru a multitude of direct and indirect pathways
