Randos Flashcards
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
VA/VL
Inferior colliculus, processing bilateral ______ information
auditory
Medial geniculate nucleus.
Axons originate in ______
inferior
colliculus
medial geniculate nucleus processes
bilateral auditory information
Fasciculus Cuneatus
Fine touch, vibration and proprioception
ipsilateral arm & hand
Fasciculus and Nucleus Gracil
Fine touch, vibration, and proprioception
ipsilateral leg & foot
Spinal Trigeminal Nuc.
Pain & temperature,
ipsilateral face
Pyramidal decussation
Corticospinal tr.; motor commands from cortex to spinal cord
Medulla
Nuc. gracilis
Axons exit the nucleus and cross the midline to enter the medial lemniscus which ends in the contralateral VPL
Fibers of the spinal trigeminal tract come from the ______ ganglion and carry pain & temp. information
ipsilateral trigeminal
Nuc. of the solitary tract:
visceral sensory nucleus; farther rostrally, it would also deal with taste information
Dorsal motor nuc. of the vagus:
preganglionic parasympathetic neurons of the vagus nerve
Hypoglossal nuc:
motoneurons innervating the tongue
Dentate Nuc.
Cells here send axons out the superior cerebellar peduncle to end in the contralateral VA/VL nucleus of the thalamus
Vestibular Nuc
Balance & acceleration information
Nuc. of the Solitary Tr.
Taste and viscerosensory informat
Hypoglossal Nuc.
Motor innervation of the tongue
Dorsal Motor Nuc. of the Vagus
Preganglionic parasympathetic neurons of the vagus nerve
Dentate Nuc.
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
Inferior Olivary Nuc.
These cells project via the contralateral inferior cerebellar peduncle to the cerebellar cortex where they end as climbing fibers.
Inferior cerebellar peduncle
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
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 \_\_\_\_\_\_\_\_\_\_
red nucleus
Medial Lemniscus originates from the _______; terminates in the ipsilateral VPL
contralateral nuc. gracilis and cuneatus
Pyramid (corticospinal tr.) originates from ________________; terminates in the contralateral spinal cord.
ipsilateral motor and premotor cortex
Inferior cerebellar peduncle originates from the contralateral ________ and from neurons of the ipsilateral Clarke’s column (spiinocerebellar tr.).
inferior olive
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 ________.
ipsilateral cerebellum
