Answer 6

Ipsilaterally to dorsal aspect of lateral white column

Question 7

In the dorsal spinocerebellar tract, after ascending where does it go to?

Answer 7

Through inferior cerebellar peduncle to the cerebellar cortex

Question 8

DRG

Question 11

In the Ventral spinocerebellar tract, where is the second order nucleus located?

Answer 11

Dorsal gray horn

Question 12

In the Ventral spinocerebellar tract, where do the fibers go to from the dorsal gray horn?

Answer 12

Crosses the AWC and continues up contralaterally

Question 13

In the Ventral spinocerebellar tract, where do the fibers go to as it has crossed the AWC and is ascending upwards?

Answer 13

Superior cerebellar peduncle

Question 14

In the Ventral spinocerebellar tract, after it has entered the superior cerebellar peduncle, where does it go next?

Answer 14

It crosses over again to the opposite cerebellum and synapses at the third order neuron in the cerebellar cortex

Answer 18

Inferior cerebellar peduncle

Question 19

In the cuneocerebellar tract, what are the fibers called that go from accessory cuneate nucleus to inferior cerebellar peduncle?

Answer 19

External arcuate fibers

Question 20

In the cuneocerebellar tract, where do the external arcuate fibers end at?

Answer 20

Cerebellar cortex
