The last component of the nervous system to be involved in this process is dendrites 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. The process starts with the activation of sensory neurons, which are responsible for detecting the stimulus (in this case, the sensation of a mosquito landing on your hand). These sensory neurons have dendrites that receive signals from sensory receptors in your skin.
2. Once the sensory neurons are activated, the signals are transmitted through their axons, which are long projections that carry the electrical impulses away from the cell body of the neuron. The axons of the activated sensory neurons transmit this information towards the central nervous system (CNS), specifically to the spinal cord or brain.
3. In the CNS, the information is processed and integrated. This involves the involvement of various neurons and structures in the brain or spinal cord.
4. To initiate a swatting response, the processed information is sent from the CNS to the motor neurons. Motor neurons are responsible for transmitting signals from the CNS to the muscles and glands in your body.
5. The motor neurons receive the signals through their dendrites, which are the branched projections that receive information from other neurons. The dendrites in motor neurons receive the signals from the CNS, specifically the brain or spinal cord.
6. Finally, once the signals are received by the dendrites in motor neurons, they are transmitted through the motor neuron's axons, which carry these signals away from the cell body of the neuron. The axons in motor neurons connect to the muscle fibers involved in the swatting action, causing them to contract and produce the desired movement.
Therefore, the correct answer to the question is: axons in motor neurons. They are the last component of the nervous system to be involved in the process, as they carry the signals from the CNS to the muscles, resulting in the swatting action.
