1

what are the functions of the anterior and posterior spinal cord

anterior cord: sensory and motor functions (light touch, pinprick and pain)

posterior cord: vibration and proprioception (joint position sense)

2

what are the functions of central and lateral spinal cord tracts

more central tracts move arms, more lateral tracts move legs

3

what are the symptoms of anterior cord syndrome

- loss of motor and sensory function below neural level
- retained proprioception and vibration sensation even below lesion

4

what are the symptoms of posterior cord syndrome

- loss of proprioception and vibration sensation below neural level - ataxia and loss of coordination
- retained motor and sensory function

5

what are the symptoms of central cord syndrome

arm problems more than legs - inverted paraplegia

6

what is a neural level

last functional level below a lesion of spinal cord

7

which nerve roots will be affected by disc prolapse in cervical and lumbar spine

cervical spine: paracentral and far lateral discs affects same roots, e.g. C6/C7 discs affect C7 n., C7/T1 discs affect C8 n.

lumbar spine: paracentral disc affects next exiting nerve root, far lateral disc affects exiting nerve root, e.g. L4/5 PC disc affects L5 n., L4/5 FL disc affects L4
