Answer 9

peripheral autonomic preganglion SNS & PNS

Question 10

cauda equina s/s include

Answer 10

1. atrophy denervation
2. no voluntary Mm control

Answer 11

no disx. touch 
no motor fx

Question 13

incomplete SCI:

Answer 13

partial dependent on what you got

Question 14

neurological fx of SCI:

Answer 14

mmt above the 3/5

Question 15

functional SCI:

Answer 15

MMT above 3+ / 5

Question 16

two abnormal interneuron activity with a SCI: :

Answer 16

exaggerated withdrawal reflex

phasic stretch hyperreflexia

Question 17

what happens to the reflexes: withdrawal / phasic in a SCI?

Answer 17

they get exaggerated / hyperreflexic

Question 18

myoplasticity of an SCI includes?

Answer 18

atrophy (sp. cord = disuse / cauda equina = denervation)
fibrosis
contractures

Question 19

cauda equina list the five s/s

Answer 19

1. atrophy of denervation
2. no voluntary Mm
3. loss of bowel and bladder
4. hyporeflexic
5. sensory sets cut = dermatomal loss

Question 20

a spastic bladder is another name for a

Answer 20

hyperreflexic bladder

Question 21

a hyperreflexic bladder is when

Answer 21

the bladder is cut above the scaral
has singals to say full but
no control so empties whenever
- empties too much = hyper

Question 22

a flaccid bladder is another name for

Answer 22

hyporeflexic bladder

Question 23

a hyporeflexic bladder is when

Answer 23

the bladder is ut from S2-S5 and doesn’t know its been cut

- fills, but can’t release so leaks out of spinchter

Question 24

list the four most common causes of SCI

Answer 24

MVA
sport injuries
falls
penetrating wounds

Question 25

spinal shock is when

Answer 25

there is a period of time after the SCI where everything below lesion is turned off: LMN shuts down non fx
= over time wears off and becomes hyperreflexic

Question 26

three bad things that happens with a SCI: ( with loss of autonomic control)

Answer 26

autonomic dysreflexia
impaired temperature
orthostatic hypotension

Question 27

orthostatic hypotension is when

Answer 27

you have impaired “ capactance” can’t squeeze venules low BP all the time
impaired “muscle pump” blood cooling in the muscles

Question 28

you have two things impaired in orthostatic hypotension =

Answer 28

“capactance” - squeezing venules

“muscle pump” - cooling blood down

Question 29

impaired temperature is due to

Answer 29

impaired shunting

impaired sweating

Question 30

autonomic dysreflexia is due to

Answer 30

unchecked fight or flight response to a visceral pain
