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)

The last component of the nervous system to be involved in this process is the axons in motor neurons.
The last component of the nervous system to be involved in this process is the axons in motor neurons.
To determine which component of the nervous system is the last to be involved in this process, we need to understand the sequence of events that occur when a mosquito lands on your hand and you swat at it.
1. When the mosquito lands on your hand, sensory neurons in the skin, known as receptor neurons, detect this stimulus.
2. The receptor neurons transmit the signal from the mosquito to the central nervous system (CNS), specifically the spinal cord or brain, through their axons.
3. In the CNS, the signal is received by interneurons, which process and integrate the information.
4. The interneurons then transmit the processed signal to the appropriate motor neurons, which are responsible for initiating a response.
5. Motor neurons carry the signal from the CNS to the relevant muscles involved in the swatting motion.
6. Finally, the muscles contract, and you swat at the mosquito.
Given this sequence of events, the last component of the nervous system to be involved in the process is the dendrites in motor neurons. These dendrites receive the signal from the interneurons and initiate the cascade of electrical impulses that ultimately result in muscle contraction and the swatting motion.
Therefore, the correct answer is: dendrites in motor neurons.
