DCML
Vibration and kinesthesia are part of the...
100
Centrifugal and centripetal
What are the two systems involved in the vascular supply to the spine?
100
Least = C spine
Lumbar
Thoracic is most stable
List spinal segments from least to most stable
100
LMN - she has flaccid paralysis
Is Gaby with an L1 AIS A SCI UMN or LMN?
200
Anterior Cord Syndrome
Loss of motor, pain, temperature, and crude touch are signs of
200
Sucal = Central
Pial = peripheral
Which specific arteries supply the central and peripheral region of the SC?
200
Highest incidence of neuro injury
Compression anteriorly and distraction posteriorly which may result in a wedge fracture
Describe a C-spine flexion injury
200
UMN
Is Lu Chen UMN or LMN?
300
Central Cord Syndrome
This syndrome typically occurs from a cervical spine injury
300
Up and out
What is the typical spread of SCI?
300
True - because it requires more force to damage this very stable section of the SC
True or False
A traumatic t-spine injury is more likely to be complete?
300
Loss of muscle pump
Why may Tom experience lightheadedness and dizziness with transfers from supine to sit and sit to stand?
400
CM involves the sacral cord and lumbar nerve roots where a CE involves the lumbar and sacral nerve roots only

500
C5 - biceps, brachialis
C6 - wrist extensors
C7 - triceps
C8 - some finger flexion
