LOCAL ANESTHESIA MOCK EXAM AND LOCAL ANESTHESIA MOCK BOARD EXAM ACTUAL EXAM 330 QUESTIONS AND CORRECT DETAILED ANSWERS GUARANTEED PASS When energy for conduction is derived from the nerve cell membrane itself and is no longer dependent on the stimulus for continuance, the conduction is considered to be: A. Below the minimal threshold level B. Above the minimal threshold level C. Self-propagating D. In the absolute refractory period - ANSWER -C. Selfpropagating The absolute refractory period occurs during the fraction of a millisecond when a nerve fiber can be excited only by a much stronger stimulus than the initial stimulus. A. True B. False - ANSWER -B. False Saltatory conduction refers to: 2 | Page A. Rapid transmission of nerve impulses along myelinated nerve fiber B.
