Question 1

Superior cerebellar peduncle 
contains axons originating in
dentate nucleus in cerebellum 
and ending in \_\_\_\_\_ as well
as axons originating in the 
interposed nucleus and 
ending in the red nucleus

Answer 1

VA/VL

Question 2

Inferior colliculus, processing bilateral ______ information

Answer 2

auditory

Question 3

Medial geniculate nucleus.

Axons originate in ______

Answer 3

inferior

colliculus

Question 4

medial geniculate nucleus processes

Answer 4

bilateral auditory information

Question 5

Fasciculus Cuneatus

Answer 5

Fine touch, vibration and proprioception

ipsilateral arm & hand

Question 6

Fasciculus and Nucleus Gracil

Answer 6

Fine touch, vibration, and proprioception

ipsilateral leg & foot

Question 7

Spinal Trigeminal Nuc.

Answer 7

Pain & temperature,

ipsilateral face

Question 8

Pyramidal decussation

Answer 8

Corticospinal tr.; motor commands from cortex to spinal cord

Medulla

Question 9

Nuc. gracilis

Answer 9

Axons exit the nucleus and cross the midline to enter the medial lemniscus which ends in the contralateral VPL

Question 10

Fibers of the spinal trigeminal tract come from the ______ ganglion and carry pain & temp. information

Answer 10

ipsilateral trigeminal

Question 11

Nuc. of the solitary tract:

Answer 11

visceral sensory nucleus; farther rostrally, it would also deal with taste information

Question 12

Dorsal motor nuc. of the vagus:

Answer 12

preganglionic parasympathetic neurons of the vagus nerve

Question 13

Hypoglossal nuc:

Answer 13

motoneurons innervating the tongue

Question 14

Dentate Nuc.

Answer 14

Cells here send axons out the superior cerebellar peduncle to end in the contralateral VA/VL nucleus of the thalamus

Question 15

Vestibular Nuc

Answer 15

Balance & acceleration information

Question 16

Nuc. of the Solitary Tr.

Answer 16

Taste and viscerosensory informat

Question 17

Hypoglossal Nuc.

Answer 17

Motor innervation of the tongue

Question 18

Dorsal Motor Nuc. of the Vagus

Answer 18

Preganglionic parasympathetic neurons of the vagus nerve

Question 19

Dentate Nuc.

Answer 19

One of the deep cerebellar nuclei. They receive input from cerebellar cortex and project via the superior cerebellar peduncle to the cerebellar target nuclei. In particular the dentate nucleus projects mostly to the VA/VL complex in the thalamus

Question 20

Inferior Olivary Nuc.

Answer 20

These cells project via the contralateral inferior cerebellar peduncle to the cerebellar cortex where they end as climbing fibers.

Question 21

Inferior cerebellar peduncle

Answer 21

originates from the contralateral inferior olive and from neurons of the ipsilateral Clarke’s column (spiinocerebellar tr.). More rostrally, the peduncle also will contain fibers from the ipsilateral vestibular nerve and nuclei. These axons end in the ipsilateral cerebellum

Question 22

Superior cerebellar peduncle 
contains axons originating in
dentate nucleus in cerebellum 
and ending in VA/VL as well
as axons originating in the 
interposed nucleus and 
ending in the \_\_\_\_\_\_\_\_\_\_

Answer 22

red nucleus

Question 23

Medial Lemniscus originates from the _______; terminates in the ipsilateral VPL

Answer 23

contralateral nuc. gracilis and cuneatus

Question 24

Pyramid (corticospinal tr.) originates from ________________; terminates in the contralateral spinal cord.

Answer 24

ipsilateral motor and premotor cortex

Question 25

Inferior cerebellar peduncle originates from the contralateral ________ and from neurons of the ipsilateral Clarke’s column (spiinocerebellar tr.).

Answer 25

inferior olive

Question 26

Inferior cerebellar peduncle originates from the contralateral inferior olive and from neurons of the ipsilateral Clarke’s column (spiinocerebellar tr.). These axons end in the ________.

Answer 26

ipsilateral cerebellum
