A bipolar stimulating probe is ideal for - (ANSWER)classification of visible neural tissue
The ______ is responsible for blood flow compensation after clamping of the internal carotid artery -
(ANSWER)Circle of Willis
Voltage out vs Voltage in - (ANSWER)amplifier gain
If obtaining SSEPs preop (clinical settings) what bandpass? - (ANSWER)30-3000 Hz
Under __________ blood and certain bodily fluids of all patients are considered potentially infectious -
(ANSWER)universal precautions
subset of standard precautions that pertains specifically to blood and fluid of patients that can transmit
bloodborne pathogens
which nerve controls motor function and has sensory distribution in the 4th and 5th metacarpal? -
(ANSWER)ulnar
during a preop study, median nerve stim is used and the patient reports discomfort. what would reduce
the pts discomfort while still maintaining adequate stimulation? - (ANSWER)decrease the stimulus
intensity below the motor threshold
(decrease the intensity until you no longer see the hand visibly move when stimulating)
what happens if you dont use electodes that arent MRI-conditional? - (ANSWER)thermal burns

accuracy) (Questions + Answers) Solved 100% Correct!!
epidural electrode is placed - (ANSWER)on top of the dura
what is the generator and vascular supply for the waveform N13? - (ANSWER)generator: spinal cord
presynaptic activity from the cervicomedullary junction
vascular supply: blood supply from the PSA
as you move caudally down the spinal cord, the TES Dwave amplitude will _____ and the latency will
______ - (ANSWER)amplitude decreases
latency increases
(the d wave cannot be recorded below T7/T9 bc the corticospinal tract becomes thinner as you go down
the cord so the amplitude becomes smaller and smaller. the latency will increase as you move down as
well due to recording further from the stimulation site. )
70% of EEG changes during CEA occur - (ANSWER)first 20 seconds after cross-clamping
Brown Sequard Syndrome = loss of pain/temperature _________, loss of motor function ________ -
(ANSWER)pain/temp loss contra
motor loss ipsi
sublaminar wires aid in what type of spinal cord manipulation - (ANSWER)translation
final exit site for the facial nerve - (ANSWER)stylomastoid foramen
impedance is the opposition to - (ANSWER)alternating current flow
