1

Knee flexion is assessing which nerve root(s) and peripheral nerve?

L5/S1 - sciatic

2

Finger abduction is assessing which nerve root(s) and peripheral nerve?

T1 - ulnar

3

What is/are the role(s) of CN V?

Sensory - facial sensation Motor (V3 only) - muscles involved in mouth opening/mastication/swallowing

4

Where do you test sensation for the L4 nerve root?

Medial malleolus

5

Knee extension is assessing which nerve root(s) and peripheral nerve?

L3/4 - femoral

6

What cranial nerve is responsible for the afferent limb of the gag reflex?

CNIX

7

Using a normal Snellen chart on the wall, how far away should the patient be standing?

6m

8

What is/are the role(s) of CN III?

Motor - movement of eye muscles (SR, IR, MR, IO, LPS) Parasympathetic - pupillary constriction (via sphincter pupillae)

9

What cranial nerve is responsible for the efferent limb of the corneal reflex?

CNVII

10

Muscle wasting and fasciculations on examination is suggestive of what type of lesion?

LMN

11

If assessing a patient with potential Parkinson's, what are the most important areas to examine?

Gait, tone, tremor, bradykinesia

12

If Weber's test lateralises to the non-affected side, what type of hearing loss does this suggest?

Sensorineural

13

A resting tremor associated with Parkinson's should resolve upon what movement?

Holding hands out in front of them and spreading fingers apart

14

What type of hearing loss is suggested by bone conduction being louder than air conduction in Rinne's test?

Conductive

15

Big toe extension is assessing which nerve root(s) and peripheral nerve?

L5 - common fibular

16

Where do you test sensation for the C6 nerve root?

Tip of thumb

17

What type of lesion will cause a non-forehead sparing facial nerve palsy?

LMN lesion e.g. Bell's palsy, Ramsay-Hunt, MS

18

What further examinations would you want to do to rule out a Parkinson's plus syndrome?

Eye movements, full neurological exams and lying/standing BP

19

What cranial nerve is responsible for the efferent limb of the gag reflex?

CNX

20

What cranial nerve is responsible for the afferent limb of the corneal reflex?

CNV1

21

What happens to reflexes in an UMN lesion?

Brisk

22

If using a hand held Snellen chart to assess visual acuity, how far away from the patient should it be held?

30cm

C5/6

29

Where do you test sensation for the C8 nerve root?

Tip of little finger

30

Where do you test sensation for the T1 nerve root?

Medial mid forearm
