Flashcards in Neurological Weakness Deck (17):
1

Name 6 causes of neurological weakness?

Tumour
Stroke
MS
Bell's Palsy
Motorneurone disease
Myasthenia gravis

2

How does the homunculus relate to neurological weakness?

A small issue in the brain by the foot area of the homunculs is not a massive issue compared to a small issure in the head area of the homunculus

3

Describe the pathway for neurones from the brain to muscle?

Upper motor neurone through internal capsule
Lower motorneurone through cranial nerve to reach the muscle

4

What nerve innervated the face and mouth, so that we can smile?

VII - facial

5

What nerve innervates the jaw so that we can open our mouths?

V - trigeminal

6

What nerve innervated the tongue so that we can stick it out?

XII - hypoglassal

7

What nerve allows us to swallow?

X - vagus
IX - glossopharyngeal

8

Where does tumour, stroke, MS cause problems in the nerve pathway?

In the brain / upper motor neurone

9

Where does Bell's Palsy cause problems in the nerve pathway?

Lower motor neurone

10

Where does myasthenia gravis cause problems in the nerve pathway?

In the muscle

11

Describe the locations for MG and motorneurone disease?

Diffuse and bilateral

12

How are neurological problems classified?

According to their duration:
mins - hours = vascular
days - weeks = infection / inflamation
week - months = tumour
months - yrs = degeneration

13

Diagnose:
If weakness is in the bottom of face only?

Upper motor neurone - Stroke / tumour

14

Diagnose:
If weakness on whole side of face?

Lower motor neurons - Bell's Palsy

15

How do we pick up most neurological weaknesses?

Looking at the asymmetry

16

Diagnose:
If weakness is affecting eyes and tongue / speech?

MG

17

What is affected facially in motorneurone disease?

speech and swallowing , not eyes
