The last component of the nervous system to be involved in the process of swatting at the mosquito is axons in motor neurons.
Here's a brief explanation: When the mosquito lands on your hand, sensory neurons detect the stimulus and send signals through their axons to the central nervous system. After processing, motor neurons then send signals through their axons to the muscles to execute the swatting action. Thus, the axons in motor neurons are the final component involved in carrying out the response.
