You see a mosquito land on your hand and swat at it. A signal passes through many parts of different neurons to make this happen. Which component of the nervous system is the last to be involved in this process? (1 point)
• dendrites in sensory neurons
• axons in motor neurons
• axons in sensory neurons
• dendrites in motor neurons
The correct answer is axons in motor neurons. Motor neurons carry signals from the central nervous system (CNS) to effectors, such as muscles, to produce a response, such as swatting at the mosquito. In this scenario, the signal passes through various components, including the dendrites in sensory neurons to detect the mosquito landing on the hand, then through the axons in sensory neurons to transmit the signal to the CNS. Finally, the axons in motor neurons are responsible for transmitting the signal from the CNS to the muscles involved in swatting. Therefore, the axons in motor neurons are the last to be involved in this process.
