An itch receptor in your skin sends a message to the brain, which then sends a message to the hand to scratch the itch. this process involves which of the following nerves, in the correct order? (2 points) question 18 options: 1) sensory nerve; motor nerve 2) motor nerve; sensory nerve 3) interneuron; efferent neuron 4) efferent neuron; interneuron

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.
