1

upper motor neurons carry impulses to or from brain?

away (descending)

2

Damage to upper motor neurons results in

increased muscle tone, loss of voluntary control, decreased coordination, hyperactive/abnormal reflexes

3

Damage to lower motor neurons results in

decreased muscle tone, absent or decreased reflexes, muscle atrophy

4

Ascending paths

Sensory, carry pain, temp (Afferent)

5

Afferent

Ascending sensory paths

6

Descending pathways

Motor, voluntary purposeful movements (efferent)

7

Efferent

Descending motor pathways

8

Muscular Dystrophy

progressive muscle degeneration and wasting

9

Duchenne's Muscular Dystrophy

loss of muscle tissue thats replaced with connective tissue; muscles deteriorate

10

Patients with Duchenne's Muscular Dystrophy have an absense of what?

Dystrophin-protein

11

Duschenne's Muscular Dystrophy s/s

weak pelvic & shoulder gait, waddling gait, toe walking, hypertrophy of calf muscles, fatigue, skeletal deformities, cardiomyopathy

12

What age does Duschenne's Muscular Dystrophy occur

3-5 yrs old

13

Acute stage of Guillain-Barre Syndrome (GBS)?

Severe rapid weakness, loss of strength, resp failure, loss of facial movement, bradycardia, hypotension, sweating, SIAH (retaining H2O &NA)

14

what happens after 2-3 weeks after initial onset of Acute stage of Guillain-Barre Syndrome (GBS)

they go into a plateau stage, their symptoms level off

15

Is Guillain-Barre Syndrome (GBS) an emergency?

yes because they don't know how fast

16

Guillain-Barre Syndrome (GBS)

Rapid muscle weakness & paralysis (disorder of the PNS), paralysis starts from the feet and goes up

17

what can cause Guillain-Barre Syndrome (GBS)

eating undercooked poultry, ebstein barr virus

18

what gets inflamed with Guillain-Barre Syndrome (GBS)

segmental demyelination of peripheral nerves causes inflammation & degeneration in sensory & motor nerve roots

19

s/s Guillain-Barre Syndrome (GBS)

Ascending paralysis, poor nerve conduction, facial nerve involvement, may have respiratory involvement

20

what system is not affected with Guillain-Barre Syndrome (GBS)

cognitive & LOC

21

Myasthenia Gravis

A chronic progressive neuromuscular disorder, it destroys, alters receptors for ACH

22

What do you need ACH for?

muscle contractions

23

Without ACH in Myasthenia Gravis what happens to muscles?

This results in voluntary muscle weakness that escalates with continued activity

24

Myasthenia Gravis s/s

Diplopia (double vision), Ptosis (drooping of eye lid), generalized muscle weakness (therefor at risk for aspiration), laryngeal involvement

25

Diplopia

double vision

26

Ptosis

drooping of eye lid

27

what system is not effect with Myasthenia Gravis

Sensory changes

28

Dianosis for Myasthenia Gravis

Edrophonium test

29

Edrophonium test

used for Myasthenia Gravis, IV Tensilon is used. It prevents the breakdon of ACH so youll see an improvement within 5 mins. If no improvement its not MG

30

IV Tensilon is used for?

Edrophonium Test, it prevents the breakdown of ACH in Myasthenia Gravis
