QUESTIONS AND CORRECT ANSWERS
BUNDLED REVIEW GUIDE
●● Coulomb's Law
Answer: Like charges repel and unlike charges attract
●● Resistance
Answer: Opposition to the flow of DIRECT current. Polarizes electrodes
if used to test the integrity of application of EEG and EP electrode
application
●● Impedance
Answer: Opposition to the flow of ALTERNATING current. Does NOT
polarize electrodes
●● Ohm's Law:
Answer: 0V= IxR (voltage = current x resistance
●● Inductance
Answer: Opposition to change in current flow
,●● List the 3 major ascending SENSORY tracts
Answer: 1. Fasciculus gracilis and Fasciculus cuneatus (medial
lemniscal pathways)
2.Spinothalamic tracts
3. Spinocerebellar tracts
●● List the three major descending MOTOR tracts
Answer: 1. Corticospinal tracts
2. Reticulospinal tracts
3. Rubrospinal tracts
●● Orthodromic
Answer: propagation toward the spinal cord in a sensory axon
●● Antidromic
Answer: action potentials propagated toward the periphery in a sensory
axon
●● SSEP decussation occurs at
Answer: Medulla Oblonga
●● Name the four parts of a neuron
Answer: 1. soma
, 2. axon
3. dendrite
4. presynaptic ternminal
●● What is another name for the cell body?
Answer: Soma
●● What is at the center of the cell body?
Answer: Nucleus
●● Axons carry nerve impulses between which two structures?
Answer: Cell body and synapse
●● Which direction does the axon transmit the nerve impulse
Answer: away from the cell body or toward the synapse
●● Myelin sheath
Answer: the covering on the axon
●● Function of the myelin sheath
Answer: rapid conduction speed
