Question 1

3 types of neuropathies

Answer 1

• mononeuropathy
• multiple mononeuropathy
• polyneuropathy

Question 2

mononeuropathy affects

Answer 2

• single nerve

- focal, one spot

Question 3

multiple mononeuropathy affects

Answer 3

• several nerves

- multifocal (at least 2 foci)

Question 4

polyneuropathy affects

Answer 4

many nerves

Question 5

mononeuropathy causes

Answer 5

• traumatic myelinopathy
• traumatic axonopathy
• traumatic severance

Question 6

multiple mononeuropathy: s/s

Answer 6

• results in a random constellation of s/s, often due to ischemia
• can happen with diabetes

Question 7

polyneuropathy movement

Answer 7

• begins distal and moves proximal

- glove and stocking distribution

Question 8

polyneuropathy pattern

Answer 8

• bilateral

- symmetric

Question 9

diabetic neuropathy progression and causes

Answer 9

• small blood vessels are damaged first

- high circulating levels of glucose and other inflammatory factors causes

Question 10

diabetic neuropathy: relationship between blood flow and nerves

Answer 10

equally bad to not have blood flow to the nerves as to other tissue

Question 11

Why is blood flow so important for nerve health?

Answer 11

deliver nutrients and oxygen to the peripheral nerves

Question 12

What happens if the nerves are stationary?

Answer 12

axoplasm “globs up” and becomes resistant to movement

Question 13

Sliding of nerve in the tissue is supported by

Answer 13

• fasciculus plexus

- mesoneurium

Question 14

fasciculus plexus shares

Answer 14

tension between nerves

Question 15

movement of nerves facilitates this type of flow

Answer 15

axoplasmic
