GENERAL TERMS

Question 1

diseases may be followed by axonal regeneration and reinnervation of muscle

Answer 1

neuronal or axonal degeneration

Question 2

occurs where there is dysfunction of schwann cells or damage to myelin sheath

some schwann cells affected, others spared

cells within this layer of the nerve replace the injured schwann cells

we also onion bulb formation

Answer 2

segmented demyelination

Question 3

sequential episodes of demyelination and remyelination leads to concentric layers of schwan cell processes

Answer 3

onion bulb formation

Question 4

primary destruction of axon with secondary disintegration of myelin sheath

Answer 4

axonal degeneration

Question 5

this type of degeneration occurs in the distal portion of the axon which has been transected

Answer 5

wallerian degeneration

Question 6

myofibers become angular and compressed by surrounding normal myofiber

a type of wallerian degeneration?

Answer 6

atrophy

Question 7

occurs when a type group becomes denervated and cannot re-innervate

a type of wallerian degeneration?

Answer 7

group atrophy

Question 8

loss of the checkerboard pattern of type 1 and 2 myofibers, results of the loss of innervation with re-innervation?

Answer 8

type grouping
