Answer:
Somatic nervous system
Explanation:
The peripheral nervous system is composed of the neurons present outside the central nervous system that is the spinal cord and the brain.
The neurons of the peripheral neurons are categorized into two types on the basis of function they are involved in that is autonomic neurons and the somatic neurons.
The somatic neurons control the voluntary action of the body by sending signals to and from the muscles to the brain.
In the question, since the neurons involved controls the voluntary action therefore the somatic nervous system is the correct answer.
Williamson ether synthesis is an organic reaction, forming an ether from an organohalide anda deprotonated alcohol(alkoxide). It involves the reaction of an alkoxide ion with a primary alky halide via SN2 reaction. The reaction to form propoxypropane using Williamson reaction is as shown
CH3CH2CHONa + CH3CH2CH2Br = C2H5CH2-O-CH2C2H5 + NaBr
Sodium propoxide 1-Bromopropane 1- Propoxypropane
The answer is foreign pathogens.
