Back 3

-UMN and LMN
-no sensory deficits
-anterior horn, lateral corticospinal tracts

Front 4

occlusion of ventral artery
-what structures are spared?

Back 4

-dorsal columns and tract of Lissauer

Front 5

Tabes dorsalis
-seen in which disease?
-degen of which structures?
-what is impaired

Back 5

-tertiary syphilis
-dorsal roots and columns
-proprioception, locomotor ataxia

Front 6

syringomyelia
-which fibers are damaged?
-loss of what sensory?

Back 6

-crossing fibers of spinothalamic tract
-bilateral of loss of pain and temperature

Front 7

vitamin B12 neuropathy, Friedrich's ataxia
-what type of damage?
-where are the lesions?
-what sensory deficits?

Back 7

-demyelination
-dorsal columns, lateral corticospinal tracts, spinocerebellar tracts

Front 8

Brown Sequard syndrome
-what damage?
-what are the ipsilateral findings? 3
-what are the contralateral findings?
-what type of damage at the level of the lesion?
-what happens if T1 is involved?

Back 8

-hemisection of spinal cord
-ipsilateral: corticospinal tract (UMN), dorsal columns, loss of sensation at the level of damage
-contra: pain and temp (spinothalamic)
-LMN signs and loss of sensation
-Horner's syndrome

Front 9

Horner's syndrome
-what are the symptoms?
-lesions above which level?
