The last component of the nervous system to be involved in the process of swatting at the mosquito is the axons in motor neurons.
When the mosquito lands, sensory neurons detect the stimulus and send signals through their axons to the spinal cord and brain. The brain then processes this information and sends a response signal down the axons of motor neurons to the muscles in your hand, prompting you to swat at the mosquito. Thus, the final step involves the axons of motor neurons.
