How does a motor neuron work when a mosquito is seen on an arm? It receives stimuli information from the skin and sends it to the brain where it is processed. It receives processed information from the brain, causing the muscles of the arm and hands to remove the mosquito from the arm. It processes information from the stimuli receiver and makes the brain aware that there is a mosquito on the arm. It makes the arm numb from the effect of the mosquito bite.

Option B, It receives processed information from the brain, causing the muscles of the arm and hands to remove the mosquito from the arm

Explanation:

A motor neuron will receive information from the central nervous system (including brain) and will direct the information to the body organ that is required to perform reflex action. While a sensory neuron carries information from the sensory organs to the central nervous system

Here, the brain shall send message to the arms through the motor neurons to remove the mosquito from the hand.

Hence, option B is the correct answer
