Neuro anatomy Flashcards
1
Q
How many of each vertebrae?
A
Think about meal times… 7am, 12pm, 5pm
Cervical - 7
thoracic - 12
Lumbar - 5
Sacrum (5, fused)
Coxyx (4, fused)
2
Q
Symptoms and signs suggesting spinal cord lesion
A
- bilateral but often asymmetrical pain / symptoms
- motor symptoms eg clumsiness
o/e:
- mixed UMN and LMN signs
- sensory level
- increased sphincter tone
- autonomic dysfunction if lesion above T6 - HTN, bradycardia, urianry retention, constipation, sweating, flushing
3
Q
Symptoms and signs cauda equina
A
- bilateral sciatic pain
- perianal numbness
- fecal incontience
- urinary dysfunction (incontience or decreased awareness of filling = retention)
o/e:
- decreased anal tone (LMN)
4
Q
Symptoms and signs radiculopathy
A
radicualr pain (sharp, shooting)
unilateral
can cause weakness (rare)
o/e
- LMN signs ONLY - this counts as “objective neuro signs” and would be acted in more quickly
5
Q
At what vertebral level is the end of the spinal cord?
A
L1 usually
6
Q
Complication of lumbar spinal stenosis
A
cauda equina
7
