3.2- Spinal Cord Syndromes Flashcards
What is injury to exactly ½ of the SC (right or left)?
What is very rare- due to violence (gun or knife)?
Brown-Sequard Syndrome affects ____________on side of lesion.
both white and gray matter
Brown-Sequard Syndrome causes what symptoms in the Dorsal Column (white matter)?
loss of light discriminating touch, kinesthetic sense, and vibration on the same side of the lesion (does not cross until the brain)
Brown-Sequard Syndrome causes what symptoms in the Lateral Column- contains Lateral Spinothalamic tract?
loss of pain and temp on the opposite side (crosses at same level)
Brown-Sequard Syndrome causes what symptoms in Lateral Corticospinal tract?
loss of upper motor neuron on same side (crosses in brain)
results in spastic paralysis on same side- hypertonic and hyperreflexic
cell bodies contained in the ____ are damaged at just that level of trauma, so the affects of cell body loss will be seen at just that level
Brown-Sequard Syndrome causes what symptoms in the dorsal horn? ventral horn?
dorsal horn- complete anesthesia same side in just that dermatome
ventral horn- flaccid in that myotome due to destroyed alpha motor neurons (hypotonic, areflexia just at that level)
What syndrome is anterior 2/3 of spinal cord affected bilaterally?
Anterior Cord Syndrome
Anterior Cord Syndrome is very common. It is often seen with ____ injury to the neck damaging the ____ directly or _____ artery.
damaging the anterior cord directly or anterior spinal artery
Anterior Cord Syndrome causes what symptoms in the lateral column?
lose pain, temp, crude touch bilaterally below lesion
Anterior Cord Syndrome causes what symptoms in the Lateral Corticospinal Tract?
spastic paralysis bilateral
Anterior Cord Syndrome causes what symptoms in the cell bodies of gray matter?
flaccid paralysis in myotome of lesion level bilaterally
Anterior Cord Syndrome does not affect what spinal structure? What symptoms are left intact?
light touch, vibration, kinesthesia intact
What is the most common spinal cord syndrome?
Central Cord Syndrome
Central Cord Syndrome affects what area?
Symptoms are not as clear cut.
“middle” of cord affected- starts centrally and spreads out
