Question 2

Electromyography (EMG) is primarily used to assess the health of which structures?

Accepted Answer

Muscles and the nerves controlling them

Answer

EMG evaluates the electrical activity of muscles and the motor nerves that control them.

Question 3

A skin biopsy in neuropathy diagnosis is most useful for evaluating which type of fibers?

Accepted Answer

Small nerve fibers

Answer

Skin biopsy quantifies intraepidermal small nerve fiber density, helpful in small fiber neuropathy.

Question 4
