1

What parts of the spinal nerve are CNS (proximally)?

Dorsal and ventral roots

2

What does the ventral root contain?

motor axons

3

What does the dorsal root contain?

sensory NEURONS

4

What parts of spinal nerves are PNS (distally)?

Dorsal and ventral rami

5

What does the white matter of the SC contain?

Ascending and Descending tracts

6

What is in the grey matter of the sc?

Dorsal horn (sensory-gate theory of pain relief)
Lateral Horn (Cell bodies of preganglionic neurons (ANS)
Ventral Horn (cell bodies of Alpha motor neurons (Motor)

7

What is the order of the meninges?

Outermost (Dura Mater), Middle (Arachnoid), Innermost (Pia Mater)

8

What are segmental signs of SC damage?

Sensory loss in dermatomes at level of lesion only
&/or
Motor loss in myotome of lesion level only

9

Are dermatomes areas unto themselves?

No, there is a lot of overlap

10

What are signs of vertical tract lesions?

Loss of fxn. below lesion, sensory impairment, motor impairment

11

How common is anterior cord syndrome?

Very. It is caused by flexion & compression of neck such as in MVAs and diving accidents

12

What is anterior cord syndrome?

damage to anterior 2/3 sc (spinothalamic tract) and corticospinal
intact posterior sc (DCML)

13

What is a spinal nerve classified as?

CNS (encased in bone)

14

Is pain and temperature sensation affected with anterior cord syndrome?

Yes

15

Is touch and proprioception intact with anterior cord syndrome?

No

16

What is central cord syndrome?

Either a small or large lesion
Small lesion-loss of pain and temp AT level of lesion (seg. sign)
Large lesion- impaired motor function in UEs

17

What does the spinal nerve consist of?

all sensory and motor axons connected with a single segment of the cord

18

What is a syndrome?

A collection of S/S that occur together
