A

ipsilateral loss of proprioception

3
Q

destruction of lateral CST

A

ipsilateral spastic paralysis, hyperreflexia, hypertonia, Babinski, clonus, disuse atrophy

4
Q

unilateral lesion of lateral spinothalamic tract

A

contralateral loss of pain and temp two levels below lesion

5
Q

transection of lateral reticulospinal tract

A

unable to void bladder, spinal shock

6
Q

destruction of anterior white commissure

A

bilateral loss of pain and temp to upper extremities (cape like)

7
Q

lesion to anterior horn

A

ipsilateral flaccid paralysis, arrefelxia, atonia, atrophy, fasciculations

8
Q

dorsal root lesion

A

ipsilateral sensory dermatomal anesthesia, possible ipsilateral diminished muscle tone/reflex

9
Q

lesion to lateral funiculus of white matter of spinal cord

A

ipsilateral UMN paralysis/paresis below level of lesion (from hitting lateral CST)

10
Q

lesion to anterior funiculus of white matter of spinal cord

A
  • contralateral loss of pain and temp two levels below lesion (lateral ALS)
  • bilateral loss of pain/temp (anterior white commissure)
  • ipsilateral lower motor paralysis at level of lesion (anterior horn)
11

bilateral pain and temperature loss C5-C6 indicates what

A

syringomyelia or central cord syndrome

A

spinal cord injury causing spinal shock

A

Brown Sequard Syndrome
