True - Core bundles innervate tissues at some distance away Resting state, stimulation, slow depolarization & firing threshold, rapid depolarization, repolarization, return to resting state - sequence that describes the events in a successful impulse generation Sensory and small nerves, then motor nerves - Local anesthesics are effective on both motor and sensory nerves.
