Which nerve fiber has slowest conduction velocity?
Type C
C fibers are unmyelinated unlike most other fibers in the nervous system.
This lack of myelination is the cause of their slow conduction velocity
Most common polyneuropathy is -
Most common polyneuropathy is diabetic sensorimotor polyneuropathy
Megavitamin-B6 syndrome has been reported in doses as low as -
Megavitamin-B6 syndrome has been reported in doses as low as 24 mg/day
Dysesthesias restricted to the fifth digit and the adjacent one-half of the fourth finger on one hand point to disorder of the -
Dysesthesias restricted to the fifth digit and the adjacent one-half of the fourth finger on one hand reliably point to disorder of the ulnar nerve， most commonly at the elbow
Inverted champagne bottle appearance seen in -
Lipodermatosclerosis
Charcot-Marie Tooth Disease
ALL of the following causes stocking neuropathy EXCEPT -
Excess vitamin B6 can cause nerve damage
In the CNS, including the spinal cord, myelin sheaths are produced by -
In the CNS, including the spinal cord, myelin sheaths are produced by oligodendrocytes and not by Schwann cells.
All of the following are CORRECT for peripheral neuropathy EXCEPT -
Toes are involved first then Fingers
Which of the following nerve fibers first involved in Peripheral Neuropathy?
Type C
Most common inherited cause of peripheral neuropathy -
Most common type inherited cause of peripheral neuropathy is Charcot-Marie-Tooth disease
This is one of the hereditary motor and sensory neuropathies.
ALL of the following are CORRECT about Wallerian degeneration EXCEPT -
Part of the axon distal to the injury (i.e. farther from the neuron's cell body) degenerates
Wallerian degeneration is an active process of degeneration that results when a nerve fiber is cut or crushed and the part of the axon distal to the injury (i.e. farther from the neuron's cell body) degenerates
