Intro to Neurodynamics and Mobilization of the Nervous System

Question 1

components of NS

Answer 1

CNS

peripheral

ANS

Question 2

CNS

Answer 2

brain and SC

Question 3

peripheral

Answer 3

nerves outside the brain and spinal cord

Question 4

ANS

Answer 4

sympathetic and parasympathetic

Question 5

the NS is a

Answer 5

continual tract

Question 6

what creates mechanical stress onto the NS

Answer 6

a person’s trunk and limb movements

Question 7

mechanical stresses can be

Answer 7

transferred and shared

Question 8

sharing of stresses

Answer 8

stresses to the PNS are transmitted to the CNS

stresses to the CNS are transmitted to the PNS

Question 9

the NS system is

Answer 9

viscoelastic and highly adaptable

Question 10

what do peripheral nerves have to normally adapt to

Answer 10

marked changes in length of the nerves

Question 11

what do nerves have to deal with

Answer 11

interfacing w/ different types of tissues

soft–> muscle and fascia

hard –> boney

Question 12

what must nerves and the associated CT do

Answer 12

lengthen and slide

Question 13

spinal N is how much longer in flexion

Answer 13

5-9 cm

Question 14

how much long is the median nerve in wrist/elbow extension

Answer 14

20%

Question 15

what protects the CNS

Answer 15

cranium

vertebral column

Question 16

what protects the PNS

Answer 16

common position of peripheral nerves

run deep and on flexor side of the limbs –> exception: common peroneal N and ulnar N

Question 17

NS adaptation to movement

Answer 17

elongation of nerve

intraneural movement

Question 18

elongation of nerve

Answer 18

nerve can elongate a lot before it begins to be stretched

movement of spine and/or extremities do not affect these tension sites

Question 19

intraneural movements

Answer 19

movement of the nerve relative to its own CT

CT allows traction forces to be distributed over the length of the nerve

Question 20

dura

Answer 20

spinal dura

Question 21

what does the dura form

Answer 21

loose sheath around the spinal cord

Question 22

what does the dura do laterally

Answer 22

surrounds spinal nerves as they exit from the intervertebral foramen

Question 23

what happens if the dura becomes adherent

Answer 23

excessive stress is produced where the spinal nerves exit

Question 24

what does excessive stress create sxs of

Answer 24

pain

impaired mobility

sensory deficits

Question 25

how do nerves respond to trauma

Answer 25

inflammatory response –> adhesion can develop –> limited mobility

Question 26

what does nerve irritability occurs via

Answer 26

tension

friction

compressive forces

redundancy

Question 27

where the sxs of nerve irritability occur

Answer 27

anywhere along the path of the nerve

nerve entrapment syndromes

Question 28

injury can occur due to

Answer 28

abnormal postures

direct trauma

indirect trauma

Question 29

abnormal postures –> injury

Answer 29

stretch

compress

tension

friction

redundancy

Question 30

direct trauma –> injury

Answer 30

direct blow or laceration of nerve

Question 30

indirect trauma –> injury

Answer 30

joint dislocation

fx

manipulation

surgery

Question 31

extremes of motion

Answer 31

places excessive traction forces on the nerve

Question 32

what can compression occur w/

Answer 32

very forceful muscle contractions

tight fascia

bony osteophytes

space occupying lesion

Question 33

electrical injuries

Answer 33

about 1/4 of people who are electrocuted had permanent nerve injuries

Question 34

what are nerves less tolerant to

Answer 34

compression
