Answer:
1) Sensory nerve; motor nerve
Explanation:
Sensory nerves are afferent nerves that send signals from the periphery of the body to the central nervous system via sensory signals (fibers). On the other hand, the so-called motor nerves (fibers) are efferent nerves that send signals from the central nervous system to the muscles or glands through stimulating signals.
When your hand itches, the sensory nerve feels the itch, sends that signal to the central nervous system which in turn sends a signal to the motor nerves to move to scratch the itch.
